Quick Start

Recommended Equipment

• DC power supplies

+5V, 100mA positive power supply (VCC)

-5.2V, 100mA negative power supply (VEE)

+5V, 100mA logic power supply (VCCO_)

+3V 1mA latch enable power supply (LE_)

• RF signal generator (e.g., MAX8685A)

• High-bandwidth oscilloscope

Procedure

The MAX9601 EV kit is fully assembled and test-

ed. Follow the steps below to verify board operation.

Caution: Do not turn on power supplies until all con-

nections are completed.

1) Set the VCC power supply to +5V. Disable VCC.

2) Connect the negative terminal of the VCC power

supply to the GND pad. Connect the positive termi-

nal of the VCC power supply to the VCC pad.

3) Set the VEE power supply to -5.2V. Disable VEE.

4) Connect the negative terminal of the VEE power

supply to the VEE pad. Connect the positive terminal

of the VEE power supply to the GND pad.

5) Set the VCCO_ power supply to +5V. Disable

VCCO_.

6) Connect the negative terminal of the VCCO_ power

supply to the GND pad. Connect the positive termi-

nal of the VCCO_ power supply to the VCCOA pad.

Short the VCCOA pad to the VCCOB pad.

7) Set the LE_ power supply to +3V. Disable LE_.

8) Connect the negative terminal of the LE_ power

supply to the GND pad. Connect the positive termi-

nal of the LE_ power supply to the LEA pad. Short

the LEA pad to the LEB pad.

9) Set the signal generator to produce an output sine-

Disable the signal generator.

10) Connect the signal generator to the edge-mount

SMA connector marked INA+.

11) Enable all power supplies. Enable the signal

generator.

12) Monitor and verify outputs QA and QA with the oscil-

loscope. The oscilloscope must be configured for

50I input termination.

13) Monitor and verify outputs QB and QB with the oscil-

loscope. The oscilloscope must be configured for

50I input termination.

Detailed Description of Hardware

Supply Voltages

The MAX9601 EV kit operates from either standard

supply levels of -5.2V/+5V or shifted levels of -4.2V/+6V.

Connect the positive and negative supply voltages to

the VCC and VEE pads, respectively. The EV kit also

requires an output driver positive supply for each chan-

nel. Connect the logic supply voltages to the VCCOA

and VCCOB pads.

Inputs

The EV kit provides INA+, INA-, INB+, and INB- SMA

connectors to access the MAX9601’s differential inputs.

The differential input stage accepts a wide range of

signals in the common-mode range from (VEE + 3V)

to (VCC - 2V) with a CMRR of 70dB (typ). All the input

traces are symmetrical and have 50I of characteristic

impedance. Each input trace has a 49.9I termination

resistor to avoid signal reflections.

Outputs

The EV kit provides QA, QA, QB, and QB SMA connec-

tors to access the MAX9601’s comparator outputs. All

the output traces are symmetrical and have 50I of char-

acteristic impedance. The output signals are referenced

to the logic supply voltage VCCO_ and have the external

components necessary to observe the PECL output. See

the Output Termination section for more details.

Hysteresis

Hysteresis can be introduced to prevent oscillation or

multiple transitions due to noise on low-slew input sig-

nals. The EV kit features resistors R7 and R16 to program

the current-controlled hysteresis. Refer to the Hysteresis

(MAX9600/MAX9601) section in the MAX9601 IC data

sheet for a more detailed description.
