3-channel Video Filter With Built-in 4-system SwitchThe 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.
