Quick Start Recommended Equipment • A DC power supply capable of supplying a voltage between 2.7V to 3.6V at 500mA • Video signal generator • Video measurement equipment (e.g., Tektronix VM700T or equivalent) Procedure The MAX9585 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 MAX9585 EV kit. 2) Connect the desired test signals from the video signal generator to the IN_A, IN_B, IN_C, and IN_D BNC connectors. The video signals at IN_A, IN_B, IN_C, and IN_D must be between 0 and 1V, approximately. SUPPLIER PHONE Murata Mfg.

Note: Indicate that you are using the MAX9585 when contacting these component suppliers. 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: MAX9585 General Description Evaluates: MAX9585 MAX9585 Evaluation Kit Detailed Description AC-Coupling the Output The outputs of the MAX9585 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 R9–R12 and install ≥ 220µF coupling capacitors on the C3–C6 pads. The MAX9585 EV kit demonstrates the MAX9585 lowpower, quad-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 MAX9585 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.
