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 50Ω controlledimpedance traces in a four-layer PC board. The EV kit can also be used to evaluate the MAX9383. Evaluates: MAX9382/MAX9383 MAX9382 Evaluation Kit Quick Start The MAX9382 EV kit is fully assembled and tested. Do not turn on the power supplies until all connections are completed. Recommended Equipment • One 450MHz (min) two-channel pulse generator (e.g., Agilent 8133A) • One 12GHz (min) bandwidth oscilloscope with internal 50Ω 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 50Ω coax cables a) Matched SMA 50Ω coax cables for inputs R and V b) Matched SMA 50Ω 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. 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. R V U D Figure 1. Waveform for R Lagging V 2 _______________________________________________________________________________________ MAX9382 Evaluation Kit 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. 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. Table 1. VEE Ranges Power Supply In order to terminate the outputs with 50Ω to (VCC - 2 V) using the 50Ω 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).
