CXA1645M

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.

The CXA1645M is designed as one kind of RGB Encoder 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.The CXA1645M is best suited to image processing of personal computers and video games.

Features of the CXA1645M are:(1)both sine wave and pulse can be input as a subcarrier;(2)built-in 75 drivers(RGB output,composite video output Y output, C output);(3)compatible with both NTSC and PAL systems;(4)single 5V power supply;(5)built-in band pass filter for the C signal and delay line for the Y signal;(6)built-in R-Y and B-Y modulator circuits;(7)built-in PAL alternate circuit;(8)burst flag generator circuit;(9)half H killer circuit.It can be used in image processing of video games and personal computers.
