RGB Encoder
CXA2075M
Description
The CXA2075M 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.
Compared to the CXA1645M, the CXA2075M has
superior points as follows:
1. The number of parts reduced (5 parts)
Clamp capacitor
Regulator capacitor resistor
Resistor for filter
2. External parts reduced by the internal TRAP
(External TRAP can be also selected)
3. Higher band of R, G, B OUT
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
