The SM5320A is a 5-channel video buffer with built-in 5th-order lowpass filters. The HD block lowpass filter cutoff frequency range can adjust from 4.10MHz to 42.7MHz*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 next-stage ADC system anti-aliasing filter. For video output systems, the filter reduces video DAC aliasing and external noise and can drive up to 300 terminating resistance. The cutoff frequency and signal input type can be controlled using an I2C-BUS*2, and the I2C slave address can be set by ADS (3-state input) to allow up to three SM5320A on the same bus. The output gain can be varied in the range of 0dB 2.1dB (max step: 0.15dB) for each Y/C block and HD block individually using the I2C-BUS. *1. When the resistor connected to ISET (RISET) is 1.8k. *2.
