DESCRIPTION
The M52390FP is a single-chip semiconductor integrated circuit
which has a function to convert R/G/B signal to NTSC/PAL
composite video signal and the superimpose function.
FEATURES
RGB encode
LPF for chroma difference signal is built-in. Cutoff frequency
control is possible by connecting a resistor externally.
Because VCA circuit is built-in, gain control at chroma block is
possible.
Carrier leak is on a low level because of built-in high-precision
modulation circuit and clamp circuit.
Burst signal and sync signal are generated within the IC.
Superimpose function
Ys IN (control input) is used for switching 2 input signals, VIDEO
IN and RGB IN.
Because high-speed analog switch is built-in, even microscopic
characters can be inserted.
Built-in an APC circuit to adjust tint of the parent picture (VIDEO
IN) and the RGB encode signal automatically.
Overall functions
A drive circuit (75
) can be configured with one transistor by
outputting the video output signal at 2V
P-P
.
This device can be used for both NTSC system and PAL system.

TV, VCR, monitor, and other AV equipments
