MAX9653EVKIT+

19-4265; Rev 0; 8/08 MAX9653 Evaluation Kit Features The MAX9653 evaluation kit (EV kit) is a fully assembled and tested surface-mount PCB that contains the MAX9653 triple-channel video-filter amplifier for highdefinition television (HDTV) applications. The filter’s passband is typically 42MHz. The MAX9653 EV kit also has shutdown control. The video inputs on the EV kit are AC-coupled; the video outputs can be AC- or DCcoupled. In addition, the MAX9653 video inputs are terminated with 75Ω and the video outputs have a 75Ω back termination resistor. The EV kit operates from a single 3.3V DC power supply. ♦ Jumper-Selectable Enable/Shutdown ♦ Single 3.3V Supply Operation ♦ Output Buffer with a 2V/V Gain ♦ High-Definition Television Video Filter ♦ AC-Coupled Inputs ♦ Standard 75Ω Input/Output Terminations ♦ Surface-Mount Components ♦ Fully Assembled and Tested Ordering Information PART TYPE MAX9653EVKIT+ EV Kit +Denotes lead-free and RoHS compliant.

The MAX9653 filter has ±1dB passband out to 42MHz and 50dB attenuation at 109MHz. The MAX9653 EV kit has three input channels to accept a full set of component video input signals. Before beginning, the following equipment is needed: • 3.3V DC power supply (VDD) capable of 50mA • Video signal generator (e.g., Tektronix TG-700 or similar) • The appropriate video measurement equipment (e.g., Tektronix VM5000) Procedure The MAX9653 EV kit is fully assembled and tested. Follow the steps below to verify board operation: 1) Verify that a shunt is placed on pins 1-2 of JU1 to enable the MAX9653. 2) Connect the outputs of the video signal generator to the Y_INPUT, PB_INPUT, and PR_INPUT BNC connectors on the MAX9653 EV kit. 3) Connect the Y_OUTPUT, PB_OUTPUT, and PR_OUTPUT BNC connectors on the EV kit to the input of the video measurement equipment. 4) Connect the power-supply ground to the GND pad on the EV kit. 5) Connect the 3.3V supply to the VDD pad on the EV kit. 6) Set the video signal generator for the desired video input signals. 7) Turn on the power supply and enable the video signal generator. The MAX9653 EV kit uses 0.1µF ceramic capacitors to AC-couple the video input signals to the MAX9653. The input capacitor stores a DC level such that the outputs are clamped to the appropriate DC voltage level. All video input terminals have a 75Ω termination to ground. The MAX9653 EV kit video outputs can be DC- or ACcoupled. By default, 0Ω resistors are installed on R7, R8, R9, and C4, C7, and C8 are open; each of the video outputs are configured to drive DC-coupled video loads. To configure the video outputs to drive the ACcoupled video loads, remove R7, R8, and R9, and install the 220µF capacitors on C4, C7, and C8. Shutdown Mode The MAX9653 EV kit provides an option to configure the MAX9653 into shutdown mode. See Table 1 for shunt positions. Table 1.
