ID-1 Detection
CXD2085M
Description
The CXD2085M is an IC which has the function of
detecting ID-1 (EIAJ, CPX1204) from the video signal.
16 pin SOP (Plastic)
Features
Can detect the ID-1 signal on the NTSC video
signal.
Includes I2C bus interface. Also, IC can operate
without the I2C bus.
Includes a 2-bit general-purpose I/O port function.
(When using I2C bus)
