RGB Encoder 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.
Features
•Single 5V power supply
•Compatible with both NTSC and PAL systems
•Built-in 75Ω drivers (RGB output, composite video output, Y output, C output)
•Both sine wave and pulse can be input as a subcarrier.
•Built-in band pass filter for the C signal and delay line for the Y signal
•Built-in R-Y and B-Y modulator circuits
•Built-in PAL alternate circuit
•Burst flag generator circuit
•Half H killer circuit
