Quick Start Recommended Equipment • A DC power supply capable of supplying a voltage between 2.7V to 3.6V at 500mA • CVBS and S-video signal generator • Video measurement equipment (e.g., Tektronix VM700T or equivalent) Procedure The MAX9588 EV kit is fully assembled and tested. Follow the steps below to verify board operation. Caution: Do not turn on the power supply until all connections are completed. 1) Connect the power supply to the pads labeled VDD and GND on the MAX9588 EV kit. 2) Connect the desired test signals from the video signal generator to the IN_A/CVBS, IN_B/LUMA(Y), and IN_C/CHROMA(C) BNC connectors. 3) Connect the output signals from the OUT_A, OUT_B, and OUT_C BNC connectors to the inputs of the video measurement equipment. 4) Turn on the power supply and verify the output signals. ________________________________________________________________ Maxim Integrated Products For pricing, delivery, and ordering information, please contact Maxim Direct at 1-888-629-4642, or visit Maxim’s website at www.maxim-ic.com. 1 Evaluates: MAX9588 General Description Evaluates: MAX9588 MAX9588 Evaluation Kit Detailed Description AC-Coupling the Output The output of the MAX9588 can be AC-coupled. To keep the highpass formed by the 150Ω equivalent resistance of the video transmission line to a corner frequency of 4.8Hz or lower, remove the 0Ω resistors on R7, R8, and R9 and install ≥ 220µF coupling capacitors on the C6, C7, and C8 pads. The MAX9588 EV kit demonstrates the MAX9588 lowpower, triple-channel video filter amplifier with integrated reconstruction filters. The EV kit operates from 2.7V to 3.6V with a 2V/V fixed gain. The MAX9588 has ±1dB (typ) passband flatness at 7MHz and 40dB attenuation at 27MHz and the outputs can be DC-coupled to a 75Ω load, which is the equivalent of two video loads, or AC-coupled to a 150Ω load.
