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.
