SM5307C
3-channel Video Buffer
OVERVIEW
The SM5307C is a 3-channel video buffer for the HD output equipment that corresponds to the 480i to 1080p
video signal standards. It can change the 5th-order lowpass filter (LPF) which is mounted on this IC, to four
modes of SD1, SD2, HD and filter-bypass mode, which corresponds to video signal. In addition, improvement
of S/N characteristic with HD band is actualized.

FUNCTIONAL DESCRIPTION
Filter Select and Filter-bypass Mode
The SM5307C is mounted the 5th-order lowpass filter (LPF), and is possible to use changing four modes of
SD1, SD2, HD and filter-bypass mode for corresponding to input video signal. The filter mode changes with
the FC1 and FC2 pins.

Disable Mode Function
The SM5307C has the disable mode function. When DISABLE pin set to “H”, The SM5307C operation
becomes disable mode. In disable mode operation, current consumption becomes up to 2.5mA and video signal
input and output pins are setting high-impedance.
