CXA1645M Overview
The CXA1645P/M is an encoder IC that converts analog RGB signals to a posite video signal. This IC has various pulse generators necessary for encoding. posite video outputs and Y/C outputs for the S terminal are obtained just by inputting posite sync, subcarrier and analog RGB signals.
CXA1645M Key Features
- Single 5V power supply
- patible with both NTSC and PAL systems
- Built-in 75Ω drivers (RGB output, posite 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
