Overview
SM5309A 3-channel Video Buffer with Built-in wideband LPF OVERVIEW The SM5309A is a 3-channel video buffer with built-in 5th-order lowpass filters.
The lowpass filter cutoff frequency range can adjust from 4MHz to 40MHz*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 300Ω load 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 SM5309A on the same bus.
