Video Aspect Ratio Identification Signal Encoder/Decoder
For the availability of this product, please contact the sales office.
The CXD2131Q is an IC that encodes and
32 pin QFP (Plastic)
decodes video aspect ratio identification signal
(conforming to EIAJ Standard CPX-1204) in the
vertical blanking interval of an NTSC video signal.
• The processing formerly carried out by the two
chips CXA1727Q and CXD2122AQ has been
consolidated into this one chip.
• Both microcomputer serial interface and I2C
interface functions are built in.
