SEIKO NPC CORPORATION —1

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-

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

SM5330A devices to be controlled simultaneously.
