Overview
ASAHIKASEI [AK8811/12] AK8811/12 NTSC/PAL Digital Video Encoder GENERAL DESCRIPTION The AK8811 and AK8812 are low voltage, low power and small packaged Digital Video Encoder.
They are suitable for a portable DVD or VCD player.
They convert ITU-R.
BT601/656 standard 8bit parallel data into analog composite video, S-Video or analog component signals Y/Cb/Cr in NTSC and PAL formats.
AK8812 and AK8811 support Macrovision Copy Protection Rev.
