SM5308AV 3-channel Video Buffer with Built-in wideband LPF OVERVIEW The SM5308AV is a 3-channel video buffer with built-in 5th-order lowpass filters. The lowpass filter cutoff frequency range can adjust from 5.0MHz to 44MHz*1 by 256 steps. 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 reduces video DAC aliasing and external noise and can drive up to two 75Ω terminating resistance. The cutoff frequency, signal input type, and output gain switching can be controlled using an I2C-BUS*2, and the I2C slave address can be set by ADS (3state input) to allow up to three SM5308AV on the same bus. *1.
