SM5330A

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

OVERVIEW

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), con-

trolled using an I

2

C 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

I

2

C BUS. The I

2

C BUS slave address is set using the ADS pin (3-state input), allowing a maximum of three

SM5330A devices to be controlled simultaneously.
