CXA1645P/M

RGB Encoder

For the availability of this product, please contact the sales office.

Description

24 pin SOP (Plastic)

24 pin DIP (Plastic)

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.

Features
