CXD2131Q - Video Aspect Ratio Identification Signal Encoder/Decoder

Description

The CXD2131Q is an IC that encodes and decodes video aspect ratio identification signal (conforming to EIAJ Standard CPX-1204) in the vertical blanking interval of an NTSC video signal.

Features

  • 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.
