HD/SD Multi Format Video Encoder with 3ch DAC

General Description

The AK8826 is a HD/SD TV Video Encoder with onchip 3-channel 10bit DAC.

As input data, in SDTV encoder mode, SMTE-125M / ITUR-R.BT601, 656 compatible Y/Cb/Cr 4:2:2 formats (8bit) are

accepted and in HDTV encoder mode, SMPTE-274M (1080i), SMPTE296M (720p) compatible Y/Cb/Cr 4:2:2 formats (8bit x 2)

are accepted.

As input data capture method, either a Synchronous mode to be made by detecting encoded EAV signal or a mode to

synchronize with externally-fed H/V SYNC signal is selectable.

Outputs of CVBS / SDY / SDC and HDY / HDPB / HDPR and R / G / B analog signal can be output exclusively.

VBI signal can be also superimposed on output in addition to Video signals by register setting.

AK8826 supports I2C compatible interface as Micro-Processor interface.
