MAX9508 Evaluation Kit Evaluates MAX9508/MAX9512 The MAX9508 evaluation kit EV kit is a fully assembled and tested surface-mount circuit board that contains a MAX9508 IC. The MAX9508 is a triple video reconstruction filter and quadruple amplifier for standard-definition television SDTV applications. The filter’s passband is 6.75MHz. The four amplifiers each have a +6dB gain and can drive a 2VP-P video signal into two DC-coupled loads to ground or one AC-coupled load. The MAX9508 EV kit can be configured to select between two sets of input signals internal or external. The EV kit provides a connector that supports bidirectional video signals. A sync tip clamped input is also available for processing external signals. The MAX9508 includes a SmartSleep feature that reduces the supply current when no video input signal is detected or when any output load is removed. The video input signals on the EV kit are DC-coupled. The video output signals from the EV kit can be DC- or AC-coupled. The MAX9508 video input terminals have a termination resistor to ground, and the output terminals have a back termination resistor. The EV kit operates from a single 2.7V to 3.6V DC power supply. The MAX9508 EV kit can also evaluate the MAX9512.
