CXA1645M

RGB Encoder 24Pin SOP

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.

Features

• Single 5V power supply

• Compatible with both NTSC and PAL systems

• Built-in 75ΩdriversRGB 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

Applications

Image processing of video games and personal computers
