The SM5302A is a 3-channel video buffer with built-in 5th-order lowpass filters. The lowpass filter cutoff frequency range can be linearly controlled from 4.8MHz to 43MHz^*1. The lowpass filter supports 480i to 1080i format, video signal equipment analog input/outputs. For video input systems, the device functions as a nextstage ADC system anti-aliasing filter. For video output systems, the filter removes video DAC aliasing and external noise and can drive a maximum of two 75Ω terminated loads. The cutoff frequency, signal input type, and output gain switching can be controlled using an I²C^*2 control bus, and the I²C slave address can be set by ADS (3-state input) to allow a maximum of three devices to be used simultaneously.
