Description

The M52390FP is a semiconductor integrated circuit that has a function for converting R, G and B signals into

NTSC/PAL composite video signals, as well as a superimpose function, on a single chip.

Features

â¢ RGB encoder-related

ï£§ Built-in LPF for color discrimination. An external resistor enables cutoff frequency control.

ï£§ An internal VCA circuit enables gain control of the chroma unit.

ï£§ A high-precision modulation circuit and clamping circuit realize low carrier leaks.

ï£§ Burst and synch signals are generated in the IC.

â¢ Superimpose-related

ï£§ YS IN (control input) enables switching between two input signals, VIDEO IN and RGB IN.

ï£§ An internal high-speed analog switch makes it possible to insert fine text.

ï£§ An internal APC circuit automatically adjusts the color phases of new screen (VIDEO IN) and RGB encoder

signals.

â¢ Overall

ï£§ The VIDEO OUT signal is output at 2 VP-P, making it possible to configure a 75 â¦ drive circuit with a single

transistor.

ï£§ Both NTSC and PAL are supported.

Application

â¢ TVs, VCRs, monitors and other audio/video devices

Recommended Operating Conditions

â¢ Power supply voltage range: 4.7 to 5.3 V

â¢ Recommended power supply voltage: 5.0 V
