M65677FP

DIGITAL NTSC/PAL ENCODER

DESCRIPTION

The M65677FP encodes CCIR601 or CCIR656 format Y/Cb/Cr data
into analog NTSC and PAL video signals, including Digital Signal
Processing functions such as Closed Caption encoding, Overlay
OSD, Anti Video Copy Processing (Note1) e.t.c. It also includes
peripheral processing function such as 10bit DAC e.t.c., so that low

cost and compact system can be realized.
