3-channel Video Filter With Built-in 4-system Switch

The SM5330A is a 4-system input switching 3-channel Video lter with 5th-order lowpass lter built-in. The lowpass lter cutoff frequency range is 5MHz to 13MHz (SD mode) or 16MHz to 40MHz (HD mode), con- trolled using an I 2C BUS*1. The lowpass lter enables the device to be utilized in the Analog input stage of Video signal equipment, functioning as an ADC system anti-aliasing lter 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 I 2C BUS. The I 2C BUS slave address is set using the ADS pin (3-state input), allowing a maximum of three SM5330A devices to be controlled simultaneously. *1.
