Save/Load Settings

All settings specified by the GUI can be saved to a file

by selecting the File_|_Save_Setup menu item located at

the front of the menu bar. Settings saved in a file can also

be loaded to the GUI and the MAX19000 using the same

procedure of selecting the File_|_Load_Setup menu item.

Use the save-and-load feature to save many different

setups, which can be recalled at a later time.

Detailed Description of Software

User-Interface Panel

The GUI contains two DCL tab sheets for channels 0

and 1 for all level, register, and control-signal settings.

The File menu item has save and load functions for all

of the settings.

Driver/Comparator/Load (DCL) Settings

DCL/Channel_0_and_DCL/Channel_1 tab sheets (Figures

1 and 2) are identical and are for channels 0 and 1,

respectively. These tab sheets contain Level_ Settings_

and DCL_Register group boxes.

Advanced User Interface

There are two methods for communicating with the

MAX19000. The first is through the windows shown in

Figures 1 and 2. The second is through the Advanced_

User_Interface window. The Advanced_User_Interface

window, available by selecting the Option_ |_ Interface_

(Advanced_User) menu item, allows execution of serial

commands manually.

Level Settings

The Level_ Settings group box contains registers for

signal level, calibration, and gain settings for VDH, VDL,

VDT, VCH, VCL, VCPH, VCPL, VCOM, VLDH, and VLDL.

Each setting is controlled by a scrollbar with a value label

to its right. Finer adjustments can be made by clicking on

the arrows on each side of the scrollbar. The scrollbars in

the Level group box have 16,384 steps corresponding to

14 bits. In the Calibration group box, the Offset scroll-

bars have 256 steps corresponding to 8 bits, and the

Gain scrollbars have 64 steps corresponding to 6 bits.

The corresponding voltage levels are also calculated

and shown in the edit boxes inside the Voltage group

box. The value, calibration, and gain selections become

effective immediately after an adjustment without hav-

ing to press the LOAD button. The value can also be

typed into the edit boxes inside the Voltage_group box.

Pressing the Enter key on the keyboard loads the values

to the device.

The Advanced_User_Interface window can also be used

as a debug tool since it is capable of manually reading

and writing to every register of the MAX19000.

Detailed Description of Hardware

The MAX19000 evaluation kit (EV kit) is a fully assembled

and tested PCB that evaluates the MAX19000 dual pin

driver. The EV kit includes SMA connections for the high-

speed digital I/Os and the MAX19000 pin-driver outputs.

The MAX19000 EV kit is connected to the PC through the

universal serial bus (USB) port.

Power Supplies

Connect the power supplies using the high-current-rated

banana jacks, J24 (-5.25V) and J20 (+15V). Common

to all power supplies should be the GND banana jack,

J22 (GND) on the MAX19000 EV kit. All power supplies

should be within the range specified on the MAX19000

IC data sheet. The MAX19000 needs only two supplies

attached to the board. All other supplies are generated

through regulators on the EV kit board.

DCL Register

The DCL_Register group box contains eight checkboxes

to control the DCL register. A checked checkbox repre-

sents a logic-high and an unchecked checkbox repre-

sents a logic-low. Any change in state of the checkbox

immediately sends the new bit setting to the device.

The DCL_ Register group box also has six drop-down

lists that control the driver output impedance, compara-

tor hysteresis, and driver/comparator cable-droop com-

pensation.

High-Speed Digital I/Os

Pin-Driver Outputs

The top and bottom edges of the PCB are populated with

end-launch SMA connectors, and are the high-speed

digital I/Os of the MAX19000. The inputs are terminated

internally to the MAX19000 IC. The outputs require termi-

nation (nominally 50I) at the end of the attached cable.

The two pin-driver outputs (DUT0 and DUT1) are through

end-launch SMA connectors on the right-edge of the

PCB. The outputs have a typical output impedance of

50I, but this can be adjusted by software.

Test Points

There are nine test points on the MAX19000 EV kit to

facilitate performance analysis and circuit modification.

These test points are listed in Table 3.

The board power supply (VRCV) is the voltage used to

terminate the comparator outputs on the MAX19000 IC.

Setting VRCV to +1.2V makes the high-speed digital I/Os

compatible with LVDS levels.

Device Ground Sense

The MAX19000 IC has the ability to sense the ground

potential at the device under test (DUT). The MAX19000

EV kit is preconfigured to have the device ground sense

(DGS) pin connected to the ground plane. If remote

sensing is desired, remove the shunt on jumper JU18

and connect the pin 1 of JU18 to the remote DUT ground.

The high-speed digital inputs (DATA0/NDATA0, RCV0/

NRCV0, DATA1/NDATA1, and RCV1/NRCV1) are intend-

ed for use with a high-speed differential signal source

such as LVDS, LVPECL, etc. If only a single-ended stim-

ulus source is available, a converter consisting of a 1:1

ratio transformer can be used to produce a differential

pair of inputs for DATA0/NDATA0 or DATA1/NDATA1. A

tri-resistor network can be used to produce a differential

logic level for RCV0/NRCV0 or RCV1/NRCV1 inputs.

Temperature Sensing

The MAX19000 EV kit provides the means to deter-

mine the MAX19000 IC’s die temperature through the

TMPSNS test point. During operation, TMPSNS should

be continuously monitored to ensure that the junction

temperature does not exceed +150NC, which corre-

sponds with +4.2V. During normal operation, a voltage

of +3V to +3.6V is typical.

The high-speed digital outputs (CL0/NCL0, CH0/NCH0,

CL1/NCL1, and CH1/NCH1) are intended for use with a

high-speed differential logic analyzer. These outputs are

internally pulled up to the VCTV voltage through internal

50I resistors. These outputs can be double-terminated

at the measurement source by external 50I resistors.
