MAX2361/MAX2363W Evaluation Kits

_______________________________________________________________________________________

Quick Start

The MAX2361/MAX2363W EV kits are fully assembled

and factory tested. Follow the instructions in the

Connections and Setup section.

Test Equipment Required

This section lists the recommended test equipment to

verify the operation of the MAX2361/MAX2363/

MAX2365. It is intended as a guide only, and substitu-

tions may be possible.

• One TCXO (Temperature-Components Crystal

Oscillator) at 19.68MHz for the PLL reference fre-

quency

• An RF spectrum analyzer with optional digital modu-

lation personality (Rohde & Schwarz FSEA30 or

equivalent)

• A power supply that can provide 250mA at +3.3V

• A power supply that can provide 50mA at +5V

• An additional voltage source for control of VGA func-

tions

• I/Q arbitrary waveform generator or CDMA generator

(Agilent E4433B or equivalent)

able parallel port

• INTF2300 interface board (supplied with EV kit)

Connections and Setup

This section provides step-by-step instructions for get-

ting the EV kit up and running in cellular and PCS

CDMA modes.

Cellular CDMA Mode

Perform the following steps to evaluate the MAX2361 in

the cellular CDMA mode:

1) Verify shunts JU1, JU2, and JU6–JU10 are in place.

2) Connect the INTF2300 interface cable as shown in

Figure 8. Note: Pin 1 of the interface cable corre-

sponds to the red wire. Pin 1 is designated in

silkscreen on each of the PC boards.

3) Connect a +3.0V power supply to VBAT. The

INTF2300 board derives its power from the MAX2361

EV kit.

4) Connect a +5.0V power supply to the header labeled

“+5V”.

5) Connect the TCXO to the REF port.

6) Connect a CDMA baseband signal generator to the

I and Q ports using BNC connectors. Set the modu-

lation to reverse-channel CDMA

7) Install and run Maxim CDMA control software.

Software is also available on the web at

www.maxim-ic.com. On the IC selection form, click

on the MAX236X control button. Select P4. Click on

register views.

8) With the MAX236X control screen active, set the reg-

isters according to Table 1.

9) Click on the Send Data button for each of the con-

trol registers located at the right of the screen.

There are eight registers that need to be down-

loaded to the IC. The Lock indicator on the screen

(and on the EV board) should be red, indicating

lock.

10) Apply 2.4V to GC via JU4.

11) Connect RFL to the spectrum analyzer. Configure

the spectrum analyzer to measure ACPR for

reverse-channel CDMA. Set the center frequency to

836MHz with a +10dBm reference level.

12) The output power should be about +9dBm after

accounting for cable and connector loss. The ACPR

at ±885kHz offset should be -54dBc, and the ACPR

at ±1.98MHz offset should be -65dBc.
