Digital Video Encorders
Video bus interface
BU9969KN
No.09067EAT02
●Description
BU9969KN is a digital video encoder IC for NTSC/PAL (ITU-R BT.601,ITU-R BT.656).
It allows captured images (e.g. downloaded or on mobile phones) to be viewed on a TV monitor. In addition, a digital filter is
built in for high image quality, and both multifunction and simple types are available for greater compatibility.
