3) Connect a cable from the computer’s serial port to

the command module (CMOD232) interface board.

Use a straight-through 9-pin male-to-female

cable. To avoid damaging the EV kit or computer,

do not use a 9-pin null-modem cable or any other

proprietary interface cable that is physically similar

to the straight-through cable.

4) Connect the provided wall-cube power supply to

the CMOD232 board.

EV Kit Software Setup

5) The MAX19700.EXE software program can be run

from the CD-ROM or hard drive. Use the

INSTALL.EXE program to copy the files and create

icons in the Windows 98/2000/XP Start menu.

EV Kit Setup

6) Verify that shunts are installed in the following locations:

JU1 (1-2)

→ CS Connected

JU1 (3-4)

→ SCLK Connected

JU1 (5-6)

→ DIN Connected

JU2 (1-2)

→ MAX19700 Enabled

JU4 (Installed)

→ Internal Reference Enabled

JU5 (1-2)

→ Digital Bus Level Shifting Enabled

JU6 (2-3)

→ Reserved

7) Connect a +3.0V, 100mA power supply to VDD.

Connect the ground terminal of this supply to GND.

8) Connect a +3.0V, 100mA power supply to CVDD.

Connect the ground terminal of this supply to GND.

9) Connect a +1.8V, 100mA power supply to OVDD.

Connect the ground terminal of this supply to

DGND.

10) Connect a +3.3V, 100mA power supply to BVCC.

Connect the ground terminal of this supply to

DGND.

11) Connect a +5V, 250mA power supply to VOP.

Connect the ground terminal of this supply to GND.

12) Connect a -5V, 250mA power supply to VON.

Connect the ground terminal of this supply to GND.

13) Carefully align the 40-pin connector of the

MAX19700 EV kit (J1) with the 40-pin header of the

CMOD232 interface board (P4). Gently press them

together.

14) The MAX19700 supports three modes of operation:

a. To connect a logic analyzer to the EV kit and

test the Rx ADCs, skip to step 15.

b. To connect a spectrum analyzer to the EV kit

and test the Tx DACs, skip to step 36.

c. To connect an ASIC or FPGA to the EV kit,

see the Configuring for ASIC/FPGA

Connection section in this document.

Rx ADC Setup

15) Ensure that a shunt is placed across pins 2 and 3

of jumper JU3.

16) Connect the clock signal generator to the input of

the clock bandpass filter.

17) Connect the output of the clock bandpass filter to

the EV kit SMA connector labeled J10.

18) Connect the first analog signal generator to the

input of the desired bandpass filter.

19) Connect the output of the bandpass filter to the EV

kit SMA connector labeled J3 (I channel).

20) Connect the second analog signal generator to the

input of the desired bandpass filter.

21) Connect the output of the bandpass filter to the EV

kit SMA connector labeled J6 (Q channel).

22) Ensure that all signal generators are phase-locked

to a common reference frequency.

23) Connect the logic analyzer to J11. See the Digital

Data Bit Locations section in this document for

header connections.

24) Set the logic analyzer to capture 10-bit CMOS data

on the falling edge for the I channel (J3) or the ris-

ing edge for the Q channel (J6).

25) Turn on the -5V power supply.

26) Turn on all remaining power supplies.

27) Plug the CMOD232 wall cube into an electrical outlet.

28) Enable the signal generators.

29) Set the clock signal generator to output a 7.5MHz

signal. The amplitude of the generator should be

sufficient to produce a 13.8dBm signal at the SMA

input of the EV kit. Insertion losses due to the series-

connected filter (step 16) and the interconnecting

cables will decrease the amount of power seen at

the EV kit input. Account for these losses when set-

ting the signal-generator amplitude.
