General Description

Features and Beneﬁts

● Evaluates the MAX4147X Sub-1GHz ISM Receiver

The MAX4147X evaluation kit (EV kit) contains a single

MAX4147X high output power VHF/UHF sub-GHz ISM/

SRD receiver designed to receive frequency-shift keying

(FSK), Gaussian GFSK, or amplitude-shift keying (ASK)

data in the 287MHz to 320MHz, 425MHz to 480MHz, and

860MHz to 960MHz frequency ranges.

● Single Input Voltage Supply from 1.8V to 3.6V

®

● Direct Interface with a MAX32630FTHR Arm

Microcontroller (MCU) Board

● Available PMOD Hardware Interface

● Windows 10-Compatible Software

The MAX41470, MAX41473, and MAX41474 EV kits oper-

ate in conjunction with an external microcontroller (MCU)

and graphical user interface (GUI) software running on

a computer. The MAX41470 uses an SPI interface for

internal register conﬁgurations while the MAX41473/74

programming and control.

The MAX41473 and MAX41474 EV kits are also designed

to operate with a simple, one-pin data interface, alleviat-

ing the need to program the part for nominal operation,

or other high-level system (PC with GUI software) hav-

ing to conﬁgure the receiver for operation. These parts

allow the user to preset the operating frequencies by

part selection and pin conﬁgurations. On the EV kit,

selecting the frequency of operation is as simple as

setting jumpers.

Power

MAX4147X EV Kit Printed Circuit Board

The MAX4147X EV kit board can be powered directly from

the FTHR board PMIC through the H1 header, directly from

the supply test points, or through the user-installed PMOD

header. A single +1.8V to +3.6V, 20mA power supply can be

connected to the board using the two wire loops (marked

3V NOM and GND) when JU5 is not populated. Jumper

JU5 selects the source of power when not using the direct

connection test points: from the L3OUT of the FTHR board

or the PMOD_VDD of the PMOD connector.

The MAX4147X EV kit PCB is manufactured on a 4-layer,

1oz copper, FR4 dielectric stack-up PCB. The board was

designed to accommodate all three versions of the ISM

receiver: MAX41470, MAX41473 and MAX41474. The

board was designed to accommodate the MAX41470

and other members of the MAX4147X family with the

use of resistors and jumpers. Layer 1 is used to route the

receiver and oscillator signals. Layer 2 is a ground layer.

Layers 3 and 4 are used to route the jumper connections

0603) and resistors (R14, R15 and R16 respectively, 0603,

470Ω recommended) to provide visual feedback of the

activity on the supply, DATA and RSSI lines. Populating

these LEDs and resistors will cause additional power con-

sumption and they are not included by default in the EV kit

assembly.

I C Pull-Ups

Resistors R8 and R9 along with jumper JU3 have been

provided as on-board pull-ups which are required for proper

2

I C interfacing and termination. These pins are open-collec-

tor (or open-drain) outputs from the MCU and need to have

pull-up resistors to operate properly. Two 4.7kΩ resistors

are pre-populated on the MAX4147XEVKIT and can be

connected to the positive supply by shorting the JU3 jumper

1-2 and 3-4. This should only be connected when the I2C/

PRESET pin is connected to logic high, thus selecting the

PMOD Interface

The MAX4147X EV kit provides a PMOD-compatible

header footprint to interface with the transmitter. The JU4

connector can be populated with a 6-pin, 100mil, right-angle

header allowing direct connections to the CSB, RSSI, SCL,

SCLK_SDA, ground, and VDD lines, making it compatible

2

I C interface mode of the MAX41473/74. It should be noted

2

that the FTHR board also has footprints for I C pull-up

resistors at R6 and R11. Both sets of pull-up resistors (on

the FTHR board and the MAX4147XEVKIT) should not be

populated simultaneously, otherwise incorrect I C signal

levels may result. Refer to Appendix II for detailed informa-

tion on Evaluation Kit Hardware Modifications.

Comport

Encoding

The Comport section provides a drop-down list of seri-

al communication ports available for connection to a

MAX4147X EV kit through a FTHR board. When the GUI

is run after connecting the EV kit hardware, the drop-down

list should default to the proper COM port. If the hardware

is connected to the computer after the GUI is started, click

on the Refresh button to scan for compatible ports. Once

the appropriate COM port is selected in the drop-down list,

click on the Connect button. (See Figure 7.)

The Encoding section allows the user to define the

type of data being transmitted. The two options here are

Manchester or NRZ and are available in the drop-down

list. (See Figure 14.)

Crystal Oscillator

The Crystal Oscillator section allows the user to match

the GUI calculation to the frequency of the crystal installed

on the MAX4147X EV kit (f ). All EV kits come prepop-

XTAL

ulated with a 16.000MHz crystal, and the default setting

in the GUI is assumed to be 16.0MHz. This value can be

adjusted to 12.8MHz or 19.2MHz and will be used when

programming frequency-based registers that are depen-

After properly connecting to the COM port with the FTHR

board, the GUI will display the revision of FTHR board

firmware detected, display a Green “LED”, and display

window. (See Figure 8.)

dent on the f

value.

XTAL

To change the reference oscillator, select the oscillator

frequency in the drop-down list. (See Figure 14.)

Voltage (1.8V to 3.3V)

The Voltage section provides a user-adjustable power

supply from the FTHR board MAX14690N power man-

agement IC (PMIC) to the MAX4147X EV kit and can be

used as the primary VDD supply. The PMIC L3OUT can

be set to voltages between 1.8V to 3.3V and it applies to

the level of the logic interface lines as well as the device

supply. (See Figure 9.)

Center Frequency

The Center Freq section is used to set the carrier or

“center” frequency of the MAX4147X (f or f ). The

value entered in this section will be used to calculate

the three-word fractional-N value programmed into the

LO_CTR_FREQ3 (0x09), LO_CTR_FREQ2 (0x0A), and

LO_CTR_FREQ1 (0x0B) registers. The GUI will calculate

the values for the PLL registers using the crystal frequency

and the following formula:

C

LO

To program the supply voltage, enter a valid level in the

Voltage field and click on the Set button. The default value

of the L3OUT voltage is 3.3V.

When using the FTHR board interface to supply the

MAX4147X EV kit with power, make sure to connect the

JU5 jumper between pins 1-2.

are selected).

To select the receiver, chose the appropriate part in the

Device Type drop-down list and click on the Set button.

(See Figure 10.)

Receiver Bandwidth

The channel filter bandwidth programmed into the device

is selected using the Receiver Bandwidth drop-down list.

The population of this list is dependent on the IF frequency

selected. The options correspond to those listed in register

IF_CHF_SEL (0x002). When 200kHz IF is selected, the

options are 170kHz, 60kHz, 26kHz, 12kHz, or 6kHz. If

400kHz IF is selected, the options are 340kHz, 120kHz,

52kHz, 24kHz, or 12kHz. Through the drop-down list, the

desired channel filter bandwidth (CHF) is selected for con-

figuration in the device. (See Figure 14.)

Modulation

The Modulation section allows the user to set the

form of modulation for the MAX4147X device. When a

MAX41473 is selected, only ASK modulation will be avail-

able in the drop-down box. Similarly, when MAX41474 is

selected, only FSK will be available in the drop-down box.

To select the modulation, chose ASK or FSK in the

Modulation drop-down list. (See Figure 14.)

Nominal FSK Deviation

Polling – WUT Duration

This is only valid when the modulation selected is FSK.

When FSK is selected, the Nominal FSK Deviation value

will be available through the drop-down list. The available

ranges in the drop-down list are based on the configura-

tion factors already defined to include the IF frequency and

the channel filter bandwidth. This will impact the DEMOD_

FSK setting in the DEMOD register (0x00).

The WUT Duration is a configurable duration that defines

the time the receiver is in the PollingRX state. This is

programmable between 0.48ms and 20.88ms. This pro-

grammed value is only used when in Polling mode and will

not impact the SlaveRX state.

Polling – WUT Duty Cycle

The WUT Duty Cycle defines the duty cycle of the detec-

tion duration versus the wait time. See the device data-

sheet for Wake-Up Timer in Self-Polling Mode diagram for

more details. The ratio is programmed in the WUT2 (0x18)

register where:

Data Rate

Enter the configured data rate of the transmitted signal into

the Data Rate field in kbps. Then click the Set button to set

the programming of the device.

As shown in Figure 18, a Manchester 2kbps signal could

look like a 2kHz square wave to represent all 1’s (or all 0’s

if shifted in phase) in Manchester encoded data. And an

NRZ 4kbps signal could look like a 2kHz square wave to

represent alternating 0’s and 1’s.

Polling – Preamble Word

The Preamble Word is the Manchester encoded word

that is compared against the incoming data stream. When

the word is detected, the PREAMB_DET bit is set in the

ISR register and the DATA line, which is held high during

the PollingRX state, will transition from high to low. This

is the interrupt for the microcontroller. It is important to

note that the preamble word is Manchester encoded. This

means that a standard square wave into the device as

the preamble would require that the preamble word be

programmed with 0x0000 or 0xFFFF (depending on the

length desired for the preamble word, as defined in the

PREAMBLE_CFG1 register through the PREAM_LEN

bits). After entering the desired value in the Preamble

Word field, click the Set button. The GUI detects the num-

ber of nibbles through the entry in the Preamble Word

field and will program the PREAMB_LEN based on this

entry.

Intention of Polling

Polling allows the system to go into a lower-power state

until the receiver and microcontroller are awakened for

active receiving of the signal. The microcontroller can be

in a pause or sleep state until the MAX4147X detects the

preamble word. When the word is detected, the interrupt

from the MAX4147X goes to the microcontroller to wake

it up for ‘listening’. The DATA line during the PollingRX

state is kept high. At the time of the detection, the DATA

line will transition low as the interrupt. The microcontroller

acknowledges the interrupt by reading the ISR (0x13)

register. If the PREAM_DET bit is set in the ISR register,

then the microcontroller places the MAX4147X into the

SlaveRX state through the STATE_CTRL1 register, the

same register used to place the device into the PollingRX

state (SLAVE_RX_EN bit versus the WUT_EN bit). When

in the SlaveRX state, the WUT Duration, WUT Duty Cycle,

and Preamble Word do not impact the operation. These

are only used in the PollingRX state.

Action Buttons – Write Registers

Action Buttons – PollingRX

The Write Registers button will take the combination

of all the settings within the GUI and write the registers

accordingly. Many of the settings within the MAX4147X

are dependent on multiple bit settings within the device.

This button will combine all settings to determine the reg-

ister writes required.

The PollingRX button will be active once the registers

are programmed, either through the Write Registers

button or the Load Config button. This button will place

the device into PollingRX mode for preamble detection.

When the preamble is detected, the microcontroller will

automatically respond appropriately as described above

and place the device into SlaveRX mode.

Action Buttons – SlaveRX

Time Plot

The SlaveRX button will be active once the registers are

programmed, either through the Write Registers button

or the Load Config button. This button will enable the

SlaveRX mode within the receiver for active data recep-

tion. In this state, the DATA test point on the EV kit will

display the data received. Since the configuration regis-

ters should not be programmed in any active state, the

GUI will grey out the other buttons and settings during

the SlaveRX state. The RX State status will move to the

Slave Receiver state. To exit the SlaveRX state, click the

SlaveRX button again.

The Time Plot button allows the user to visually see

the DATA pin displayed in a plot. This plot works best at

around the 10kbps rate and lower for proper oversam-

pling of the received signal.

The StartRF buttons should be clicked to begin the dis-

play. After it is running, the StopRF can be clicked to stop

the sampling. Clicking Clear Plot will clear the current

The right-hand side of the Register Interface section

displays the content of the selected device register. At

the top of the block, a header displays the name of the

selected register (eg “STATE_CTRL1”), the “Index” or

address of the register in both decimal (“0d”) and hexa-

decimal (“0000h”) form.

.xml File

The register descriptions for the MAX4147X GUI are

available in an .xml file which is stored with the executable

in the application directory. The default file loaded when

the GUI is initialized is MAX4147X_Registers.XML.

This file can be edited as needed to adjust the names of

fields, provide simple indicators to the GUI user, or allow

for flexible updates to the GUI interface in the future.

The body of this section shows a table with the names of

the individual bits for the selected 8b register along with

the current value programmed into each bit or bit group.

The remaining portion of the body shows a table with the

bit indexes, the type of register (write/read), the name of

the bit or bit group, the Reset value, and a description of

the bit or bit group.

Use Cases

Two Interface Modes for

Data Transmission and Control

Read and Write Registers

The MAX4147X allows a great deal of flexibility when it

comes to receiving data. Typically, the fewer pins used to

interface with the device, the simpler it is to control and

transmit data.

Most of the registers in the MAX4147X are both readable

and writable. The read-only registers are RSSI (0x10),

FEI (0x11), PDF_OUT (0x12), ISR (0x13), STATE_CTRL2

(0x15), PART_NUM (0x1E), and REV_NUM (0x1F).

Writing values to a register can be accomplished by

selecting the register of interest, typing a Hex or Dec

value into the Value field, and clicking on the Write

Register X button (where X is the decimal address of the

register). Reading the register content is similar: select

the register of interest and click on the Read Register X

button.

Preset Mode

Preset mode is the simplest interface of the three options.

It relies on the part number to choose the modulation

(MAX41473 for ASK; MAX41474 for FSK) and jumper

settings (or tri-level pin connections) to configure the part

for a defined carrier frequency (See Tables 4 and 5). With

the Preset mode, the data rate and frequency deviation,

in the case of FSK modulation, need to be within expected

ranges for proper operation.

Register Bit Field

Individual bits or bit groups can be programmed without

having to enter the full value of the register. To program

a bit or group of bits, first select the register of interest

(WUT2, 0x18 for example), next select the bit or bit group

to be changed (TSBY_TDET_RATIO as an example),

enter the binary code for the new value (0000011b), and

hit Enter—the new value will automatically be reflected in

the Value field and will be written to the device.

2

I C Mode

2

The I C interface mode allows the user to access the

internal registers of the MAX41473/74 devices, permitting

full control over the receive frequency, data rate, thresh-

olds, bandwidths, etc.

This mode only requires two digital pins to interface with

the transmitter but has a more complicated, packet-based

protocol for interacting with the device. Once configured

data line (SDA) and a serial-clock line (SCL). SDA and

SCL facilitate bidirectional communication between the

MAX41473/74 and the master (microcontroller) at clock

frequencies up to 1MHz. The master device initiates a

data transfer on the bus and generates the SCL signal to

permit data transfer. The MAX41473/74 functions as an

One bit transfers during each SCL clock cycle. A minimum

of nine clock cycles is required to transfer a byte into or

gramed to power-down into one of three low-current,

non-receiving states after completing a transmission:

Shutdown, Sleep, and Standby modes.

Shutdown is the lowest-current power-down state and is

the default condition for all devices. No programming of

the device can happen in the Shutdown state, and any

previous programming is lost. Sleep allows the interface

to be awake, but without the internal clocks running.

Standby allows the receiver to start up quicker than

shutdown by keeping the crystal oscillator circuit running.

Standby is the proper state to configure the device for

operation.

2

All the MAX41473/74 devices are identified with an I C

address of 0xD6 for write and 0xD7 for read sequences.

Packet transmission is described in the various device

2

datasheets within the “Two-Wire I C Serial Interface”

section.

SPI Mode

To set the power-down state, drive the PWRDN pin high.

To transition to Sleep state, drive the PWRDN pin low.

To transition to the Standby state, program the STATE_

CTRL1 (0x14) EN_XO bit to a 1b.

The SPI interface is only available on the MAX41470

device. Similar to the I C devices, the SPI interface allows

access to the internal registers of the receiver. This per-

mits the user to have full control over the same proper-

ties of over the receive frequency, data rate, thresholds,

bandwidths, etc.

Chip ID

Register PART_NUM (0x1E) provides a readable iden-

tification number for the device part number. With the

EN_XO=’1’, the MAX41470 device ID value will be report-

ed as 0x70. When communicating with a MAX41473

The MAX41470 device allows for a 3-wire read/write

interface. The transaction is defined by the CSB low cycle

a. When the Reset button is pressed, the microcontroller will restart and the newly programmed application will

begin to run, or you can disconnect and reconnect the USB cable if using a PC for power.

The latest information and these firmware update instructions can be found on the MAX32630FTHR board mBed web

site or by visiting the mBed home page and searching for “MAX32630FTHR”.

If you do not have an mbed account, choose Signup and create your mbed account. Otherwise, log in with your normal

username and password. This will give you access to the website, tools, libraries, and documentation.

You must load the matching HDK image (MAX32630FTHR DAPLINL image) for the platform you are programming in

order for drag-n-drop programming to work.

Appendix II – Hardware Modiﬁcations

2

I C Pull-Up Resistors

To accommodate the various operating modes of the MAX4147X products on one board, the shared digital pins have

many interface modes over which they operate.

To properly establish the open-drain topology of the two-pin serial interface the user must have the SDA and SCL lines

pulled-up to the supply voltage. The resistor footprints: R8 and R9 are provided on the MAX4147XEVKIT for this purpose.

By connecting JU3 (1-2 and 3-4) both lines will be pulled-up to the VDD supply.

2

Figure A2-1. I C Pull-Up Resistors

These pull-ups should only be connected when the I2C/PRESET pin is connected to VDD (JU2 1-2), thus selecting the

2

I C interface mode of the MAX4147X.

2

It should be noted that the FTHR board also has footprints for I C pull-up resistors at R6 and R11. Both sets of pull-up

resistors (on the FTHR board and the MAX4147XEVKIT) should not be populated simultaneously, otherwise incorrect

2

I C signal levels may result. Likewise, if other I C slaves are added to the bus, only one set of pull-up resistors should

be used.

PMOD Header Interface

The MAX4147X EV kit provides a PMOD-compatible header footprint, which provides yet another built-in interface to the

transmitter. The JU4 connector can be populated with a 6-pin, 100mil, right-angle header such as a SAMTEC TSW-106-

25-T-S-RA, allowing direct connections to the CSB/I2C, SDIO/RSSI, SCL, SCLK/SDA, ground, and VDD lines.

The PMOD interface can be used in combination with the Maxim MAX32600MBED kit and the MAXREFDES72# Arduino

Uno R3-to-PMOD shield adaptor. When using the PMOD interface to supply the MAX4147X EV kit with power, be sure

to connect the JU1 jumper between pins 2-3.
