Integrated, Dual RF Transceiver
with Observation Path
AD9375
Data Sheet
The transceiver consists of wideband direct conversion signal
paths with state-of-the-art noise figure and linearity. Each complete
Rx and Tx subsystem includes dc offset correction, quadrature error
correction (QEC), and programmable digital filters, eliminating
the need for these functions in the digital baseband. Several
auxiliary functions such as an auxiliary analog-to-digital converter
(ADC), auxiliary digital-to-analog converters (DACs), and general-
purpose input/outputs (GPIOs) are integrated to provide additional
monitoring and control capability.
FEATURES
Dual differential Tx
Dual differential Rx
Observation receiver with 2 inputs
Fully integrated, ultralow power DPD actuator and adaptation
engine for PA linearization
Sniffer receiver with 3 inputs
Tunable range: 300 MHz to 6000 MHz
Linearization signal BW to 40 MHz
Tx synthesis BW to 250 MHz
An ORx channel with two inputs is included to monitor each Tx
output and implement calibration applications. This channel also
connects to three sniffer receiver (SnRx) inputs that can monitor
radio activity in different bands.
Rx BW: 8 MHz to 100 MHz
Supports FDD and TDD operation
Fully integrated independent fractional-N RF synthesizers for
Tx, Rx, ORx, and clock generation
JESD204B digital interface
The high speed JESD204B interface supports lane rates up to
6144 Mbps. Four lanes are dedicated to the transmitters and four
lanes are dedicated to the receiver and observation receiver channels.
APPLICATIONS
3G/4G small cell base transceiver station (BTS)
3G/4G massive MIMO/active antenna systems
The fully integrated phase-locked loops (PLLs) provide high
performance, low power, fractional-N frequency synthesis for
the Tx, the Rx, the ORx, and the clock sections. Careful design
and layout techniques provide the isolation demanded in high
performance base station applications. All voltage controlled
oscillator (VCO) and loop filter components are integrated to
minimize the external component count.
GENERAL DESCRIPTION
The AD9375 is a highly integrated, wideband radio frequency (RF)
transceiver offering dual-channel transmitters (Tx) and receivers
(Rx), integrated synthesizers, a fully integrated digital predistortion
(DPD) actuator and adaptation engine, and digital signal processing
functions. The IC delivers a versatile combination of high
performance and low power consumption required by 3G/4G
small cell and massive multiple input, multiple output (MIMO)
equipment in both frequency division duplex (FDD) and time
division duplex (TDD) applications. The AD9375 operates from
300 MHz to 6000 MHz, covering most of the licensed and unlicensed
cellular bands. The DPD algorithm supports linearization on
signal bandwidths up to 40 MHz depending on the power amplifier
(PA) characteristics (for example, two adjacent 20 MHz carriers).
The IC supports Rx bandwidths up to 100 MHz. It also supports
observation receiver (ORx) and Tx synthesis bandwidths up to
250 MHz to accommodate digital correction algorithms.
The device contains a fully integrated, low power DPD actuator
and adaptation engine for use in PA linearization. The DPD feature
enables use of high efficiency PAs, significantly reducing the power
consumption of small cell base station radios while also reducing
the number of JESD204B lanes necessary to interface with baseband
processors.
A 1.3 V supply is required to power the AD9375 core, and a
standard 4-wire serial port controls it. Other voltage supplies
provide proper digital interface levels and optimize transmitter
and auxiliary converter performance. The
AD9375 is packaged in a
12 mm × 12 mm, 196-ball chip scale ball grid array (CSP_BGA).

2 Synthesis BW) is the extended bandwidth used by digital correction algorithms to measure conditions and generate compensation.
3 Quadrature error correction (QEC) is the system for minimizing quadrature images of a desired signal.
4 Local oscillator leakage (LOL) is a measure of the amount of the LO signal that is passed from a mixer with the desired signal.
5 Adjacent channel level reduction (ACLR) is a measure of the amount of power from the desired signal leaking into an adjacent channel.
6 dBFS represents the ratio of the actual output signal to the maximum possible output level for a continuous wave output signal at the given RF attenuation setting.
7 Continuous wave (CW) is a single frequency signal.
8 Note that the input signal power limit does not correspond to 0 dBFS at the digital output because of the nature of the continuous time Σ-Δ ADCs. Unlike the hard
clipping characteristic of pipeline ADCs, these converters exhibit a soft overload behavior when the input approaches the maximum level.
9 Signal-to-noise ratio is limited by the baseband quantization noise.

AD9375
Data Sheet
THEORY OF OPERATION
The AD9375 is a highly integrated RF transceiver that can be
configured for a wide range of applications. The device integrates
all the RF, mixed-signal, and digital blocks necessary to provide
transmit and receive functions in a single device. Programmability
allows the two receiver channels and two transmitter channels
to be used in TDD and FDD systems for 3G and 4G cellular
standards.
RECEIVER (Rx)
The AD9375 contains dual receiver channels. Each Rx channel
is a direct conversion system that contains a programmable
attenuator stage, followed by matched I and Q mixers that
downconvert received signals to baseband for digitization.
To achieve gain control, a programmed gain index map is
implemented. This gain map distributes attenuation among the
various Rx blocks for optimal performance at each power level.
In addition, support is available for both automatic and manual
gain control modes.
The observation receiver channel has two inputs for use in
monitoring the transmitter outputs. This channel has a wide
channel bandwidth that receives the entire transmit band and
feeds it back to the digital section for error correction purposes.
In addition, three sniffer receiver inputs can monitor different
radio frequency bands (one at a time). These channels share the
baseband ADC and digital processing with the two ORx inputs.
The receiver includes Σ-Δ ADCs and adjustable sample rates
that produce data streams from the received signals. The signals
can be conditioned further by a series of decimation filters and
a fully programmable 72-tap FIR filter with additional decimation
settings. The sample rate of each digital filter block is adjustable
by changing the decimation factors to produce the desired
output data rate.
The AD9375 contains four high speed serial interface links for
the transmit chain and four high speed serial interface links
shared by the Rx, ORx, and SnRx channels (JESD204B,
Subclass 1 compliant), providing a low pin count and reliable
data interface to a field-programmable gate array (FPGA) or
other custom integrated baseband solutions.
OBSERVATION RECEIVER (ORx)
The ORx operates in a similar manner to the main receivers.
Each input is differential and uses a dedicated mixer. The ORx
inputs share a baseband ADC and baseband section; therefore,
only one can be active at any time. The mixed signal and digital
section is identical in design and operation to the main receiver
channels. This channel can monitor the Tx channels and
implement error correction functions. It can also be used as a
general-purpose receiver.
The AD9375 also provides self calibration for dc offset and
quadrature error correction to maintain a high performance
level under varying temperatures and input signal conditions.
The device includes test modes that allow system designers to
debug designs during prototyping and optimize radio
configurations.
TRANSMITTER (Tx)
SNIFFER RECEIVER (SnRx)
The AD9375 employs a direct conversion transmitter
architecture consisting of two identical and independently
controlled channels that provide all the digital processing,
mixed-signal, and RF blocks necessary to implement a direct
conversion system. Both channels share a common frequency
synthesizer.
The sniffer receiver provides three differential inputs that can
monitor different frequency bands. Each input has a low noise
amplifier (LNA) that is multiplexed to feed a single mixer. The
output of this mixer stage is multiplexed with the ORx receiver
mixers to feed the same baseband section. The SnRx bandwidth
is limited to 20 MHz. This receiver can also be used as a general-
purpose receiver if the bandwidth and RF performance are
acceptable for a given application. The sniffer channel is also
limited to operation from 300 MHz to 4000 MHz. Performance
cannot be guaranteed for LO settings above 4000 MHz.
The digital data from the JESD204B lanes pass through a fully
programmable 96-tap FIR filter with optional interpolation.
The FIR output is sent to a series of conversion filters that
provide additional filtering and data rate interpolation prior to
reaching the DAC. Each DAC has an adjustable sample rate and
is linear up to full scale.
These receiver inputs also provide an LNA bypass mode that
removes the gain of the LNA when large signals are present.
Note that no requirements for the LNA bypass mode are included
in Table 1; performance specifications are only relative to the
scenario in which the LNA is enabled.
Once converted to baseband analog signals, the in-phase (I) and
quadrature (Q) signals are filtered to remove sampling artifacts,
and then the signals are fed to the upconversion mixers. At the
mixer stage, the I and Q signals are recombined and modulated
onto the carrier frequency for transmission to the output stage.
Each transmit chain provides a wide attenuation adjustment
range with fine granularity to help designers optimize SNR.
CLOCK INPUT
The AD9375 requires a differential clock connected to the
DEV_CLK_IN+/DEV_CLK_IN− pins. The frequency of the
clock input must be between 10 MHz and 320 MHz, and it must
have very low phase noise because this signal generates the RF
local oscillator and internal sampling clocks.

SYNTHESIZERS
AUXILIARY CONVERTERS
RF PLL
Auxiliary ADC Inputs (AUXADC_x)
The AD9375 contains three fractional-N PLLs to generate the
RF LOs used by the transmitter, receiver, and observation
receiver. The PLL incorporates an internal VCO and loop filter
that require no external components. The internal VCO LDO
regulators eliminate the need for additional external power
supplies for the PLLs. These regulators only require an external
bypass capacitor for each supply.
The AD9375 contains an auxiliary ADC that is multiplexed to four
input pins (AUXADC_0 through AUXADC_3). This block can
monitor system voltages without adding additional components.
The auxiliary ADC is 12 bits with an input voltage range of 0.05 V
to VDDA_3P3 − 0.05 V. When enabled, the auxiliary ADC is
free running. Software reads of the output value provide the last
value latched at the ADC output.
Clock PLL
Auxiliary DACs (AUXDAC_x)
The AD9375 contains a PLL synthesizer that generates all of the
baseband related clock signals and SERDES clocks. This PLL is
programmed based on the data rate and sample rate requirements
of the system.
The AD9375 contains 10 identical auxiliary DACs (AUXDAC_0 to
AUXDAC_9) that can supply bias voltages, analog control voltages,
or other system functionality. The inputs of these auxiliary DACs
(AUXDAC_0 to AUXDAC_9) are multiplexed with the GPIO_
3P3_x pins according to Table 7. The auxiliary DACs are 10 bits,
have an output voltage range of approximately 0.5 V to 3.0 V,
and have a current drive of 10 mA.
SERIAL PERIPHERAL INTERFACE (SPI)
The AD9375 uses a SPI to communicate with the baseband
processor (BBP). This interface can be configured as a 4-wire
interface with dedicated receive and transmit ports, or it can be
configured as a 3-wire interface with a bidirectional data
communications port. This bus allows the BBP to set all device
control parameters using a simple address data serial bus protocol.

Write commands follow a 24-bit format. The first bit sets the
bus direction of the bus transfer. The next 15 bits set the address
where data is written. The final eight bits are the data being
transferred to the specific register address.
Read commands follow a similar format with the exception that
the first 16 bits are transferred on the SDIO pin, and the final
eight bits are read from the AD9375, either on the SDO pin in
4-wire mode or on the SDIO pin in 3-wire mode.
GPIO_x AND GPIO_3P3_x PINS
The AD9375 general-purpose input/output signals referenced
to the VDD_IF supply can be configured for numerous functions.
Some of these pins, when configured as outputs, are used by the
BBP as real-time signals to provide a number of internal settings
and measurements. This configuration allows the BBP to monitor
receiver performance in different situations. A pointer register
selects the information that is output to these pins. Signals used
for manual gain mode, calibration flags, state machine states,
and various receiver parameters are among the outputs that
can be monitored on these pins. In addition, certain pins can
be configured as inputs and used in various functions such as
setting the receiver gain in real time.
The GPIO_3P3_x pins are referenced to the VDDA_3P3 supply.
These pins can provide control signals to other components
such as voltage gain amplifiers (VGAs) or attenuators in the RF
section that typically use a higher reference voltage.

JESD204B DATA INTERFACE
POWER SUPPLY SEQUENCE
The digital data interface for the AD9375 uses JEDEC Standard
JESD204B Subclass 1. The serial interface operates at speeds of
up to 6144 Mbps. The benefits of the JESD204B interface
include a reduction in required board area for data interface
routing and smaller package options due to the need for fewer
pins. Digital filtering is included in all receiver and transmitter
paths to provide proper signal conditioning and sampling rates
to meet the JESD204B data requirements. Examples of the
digital filtering configurations for the Tx and Rx paths are
shown in Figure 230 and Figure 231, respectively.
The AD9375 requires a specific power-up sequence to avoid
undesired power-up currents. The optimal power-on sequence
starts the process by powering up the VDIG and the VDDA_1P3
(analog) supplies simultaneously. If they cannot power up
simultaneously, the VDIG supply must power up first. The
VDDA_3P3, VDDA_1P8, and JESD_VTT_DES supplies must
then power up after the VDIG and VDDA_1P3 supplies. Note
that the VDD_IF supply can power up at any time. It is also
RESET
recommended to toggle the
signal after power has
stabilized prior to configuration. Follow the reverse order of
the power-up sequence to power down.

DIGITAL PREDISTORTION (DPD)
DPD
NO DPD
This device provides a fully integrated DPD function that
linearizes the output of the power amplifier (PA) of the transmit
system by altering the digital waveform to compensate for
nonlinearities in the PA response. Both the DPD actuator and
coefficient calculation engine are integrated. This functionality
uses the ORx channel to monitor the output of the PA and
calculates the appropriate predistortion to linearize the output.
The integrated DPD capability allows the system to drive the PA
closer to saturation, enabling a higher efficiency PA while
maintaining linearity. The DPD is optimized for small cell PAs
with rms output powers in the 250 mW to 10 W range and for a
maximum occupied signal bandwidth of 40 MHz. The
additional power consumed by the DPD block when enabled is
less than 100 mW.

Performance enhancement is shown in Figure 232 for a 20 MHz
LTE signal and in Figure 233 for a 40 MHz LTE output. In both
cases, a Band 7 Skyworks SKY66297 high efficiency PA is used
to demonstrate the adjacent channel level reduction (ACLR)
improvement for a particular device. Table 9 and Table 10 show
the details of ACLR improvement that are achieved for these two
scenarios when DPD is activated. Note that the magnitude of
improvement in ACLR is heavily PA dependent and generally
degrades as signal bandwidth increases.
