CXA1645P/M
RGB Encoder
For the availability of this product, please contact the sales office.
Description
The CXA1645P/M is an encoder IC that converts
analog RGB signals to a composite video signal. This
IC has various pulse generators necessary for
encoding. Composite video outputs and Y/C outputs for
the S terminal are obtained just by inputting composite
sync, subcarrier and analog RGB signals.
It is best suited to image processing of personal
computers and video games.
24 pin DIP (Plastic)
24 pin SOP (Plastic)
Features
Single 5V power supply
Compatible with both NTSC and PAL systems
Built-in 75drivers
(RGB output, composite video output, Y output, C
output)
