AK8859VN
NTSC/PAL/SECAM Digital Video Decoder
Overview
The AK8859VN is a single-chip digital video decoder for composite and S-video signals. Its output data is in
YCbCr format and compliant with ITU-R BT.601 and ITU-R BT.656 standard interface. Its output also
included HD / VD / FIELD and DVALID signals. Its operational temperature is between range of -40°C ~
105°C. Microprocessor access is via I2C interface.
