The SM5330A is a 4-system input switching 3-channel video filter with 5th-order lowpass filter built-in. The lowpass filter cutoff frequency range is 5MHz to 13MHz(SD mode) or 16MHz to 40MHz (HD mode), controlled using an I²C BUS^*1. The lowpass filter enables the device to be utilized in the analog input stage of video signal equipment, functioning as an ADC system anti-aliasing filter for 480i to 1080i signal systems. The signal input type and input system switching, in addition to the cutoff frequency, can be controlled using the I²C BUS. The I²C BUS slave address is set using the ADS pin (3-state input), allowing a maximum of three SM5330A devices to be controlled simultaneously.
