CXA2075M
RGB Encoder
Description
24 pin SOP (Plastic)
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
Applications
Video games and personal computers
Regulator capacitor resistor
Resistor for filter
Structure
Bipolar silicon monolithic IC
2. External parts reduced by the internal TRAP
(External TRAP can be also selected)
3. Higher band of R, G, B OUT
