RGB Encoder
For the availability of this product, please contact the sales office.
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 75 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
Applications
Image processing of video games and personal
computers
