| 19-2314; Rev 0; 1/02 MAX9382 Evaluation Kit General Description The MAX9382 evaluation kit (EV kit) includes the MAX9382, a high-speed PECL/ECL phase-frequency detector. The EV kit evaluates the MAX9382, which compares single-ended reference (R) and VCO (V) inputs and produces pulse streams on differential up (U) and down (D) outputs, depending on the input phase or frequency difference. The EV kit operates up to 450MHz. The MAX9382 EV kit is designed with 50 controlledimpedance traces in a four-layer PC board. The EV kit can also be used to evaluate the MAX9383. o Controlled 50 Microstrip Traces o Equal Input Trace Lengths o Output Trace Lengths Matched to <2mils o Board Frequency: Up to 450MHz o PECL/ECL Supply o 8-Pin SO Package o Fully Assembled and Tested Features Evaluates: MAX9382/MAX9383 Ordering Information PART MAX9382EVKIT TEMP RANGE 0C to +70C IC PACKAGE 8 SO Note: To evaluate the MAX9383, request a MAX9383ESA free sample with the MAX9382EVKIT.

MAX9382 Evaluation Kit Evaluates: MAX9382/MAX9383 Quick Start The MAX9382 EV kit is fully assembled and tested. Do not turn on the power supplies until all connections are completed. 2) Connect a 2.0V power supply to the VCC pad. Set the supply to 2.00V. Connect the supply ground to the GND pad closest to VCC. 3) Connect a -2.5V adjustable power supply to the pad labeled VEE. Set the supply to -2.5V. Connect the supply ground to the GND pad closest to VEE. 4) Connect one pair of matched coax cables to the pulse generator's noninverting outputs. Connect the other end of the cables to R and V on the EV kit. 5) Adjust the signal generator to the following settings: a) VIH = 1.0V b) VIL = 0.4V c) Duty cycle = 50% d) Frequency = 450MHz e) Set R lagging V = 600ps 6) Turn on the power supplies, enable the generator, and verify that the output signals meet the following specifications: a) VOH: 965mV < VOH < 1.12V b) VOL: 190mV < VOL < 380mV The U and D waveforms should be similar to Figure 1. Note: For other input levels, refer to the MAX9382/ MAX9383 data sheet, setting VCC = 2.0V. Recommended Equipment * * One 450MHz (min) two-channel pulse generator (e.g., Agilent 8133A) One 12GHz (min) bandwidth oscilloscope with internal 50 input termination (e.g., Tektronix 1180IC digital sampling oscilloscope with SD-24 sampling head) Two power supplies a) One 2.0V with 500mA current capability b) One adjustable -3.5V to -2.2V with 500mA current capability * Matched male-SMA-to-male-SMA 50 coax cables a) Matched SMA 50 coax cables for inputs R and V b) Matched SMA 50 coax cables for outputs U and D * Evaluating the MAX9382 at the Same Frequency with Different Phase 1) Connect two matched coax cables to the oscilloscope. Connect the other end of the cables to U and D on the EV kit board. R V U D Figure 1. Waveform for R Lagging V 2 _______________________________________________________________________________________ MAX9382 Evaluation Kit Detailed Description The MAX9382 EV kit contains the MAX9382, a highspeed PECL/ECL phase-frequency detector. The EV kit compares two single-ended inputs, R (reference) and V (VCO), and produces pulse streams on differential up (U) and down (D) outputs. When integrated, the difference of the output pulse streams provides a control voltage proportional to the input phase or frequency difference. Evaluating the MAX9383 The MAX9382 EV kit can be used to evaluate the MAX9383, a high-speed phase-frequency detector with a supply range different from the MAX9382. To evaluate the MAX9383, replace the MAX9382ESA with a MAX9383ESA. Table 1 shows the VEE ranges for the MAX9382 and MAX9383 when used with the MAX9382 EV kit. Evaluates: MAX9382/MAX9383 Power Supply In order to terminate the outputs with 50 to (VCC - 2 V) using the 50 oscilloscope input termination, VCC is set to 2.0V. In an actual application, VCC and VEE can have different supplies (refer to the MAX9382/MAX9383 data sheet). Table 1.
