MITSUBISHI ICs (AV COMMON)

M52390FP

NTSC/PAL ENCODER

DESCRIPTION

PIN CONFIGURATION (TOP VIEW)

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.

•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.

(Lead pitch:1.27mm)

Superimpose function

•Ys IN (control input) is used for switching 2 input signals, VIDEO

IN and RGB IN.

APPLICATION

•Because high-speed analog switch is built-in, even microscopic

characters can be inserted.

TV, VCR, monitor, and other AV equipments

•Built-in an APC circuit to adjust tint of the parent picture (VIDEO

IN) and the RGB encode signal automatically.

RECOMMENDED OPERATING CONDITION

Supply voltage range .................................................... 4.7 to 5.3V

Rated supply voltage ................................................................ 5V

Overall functions

•A drive circuit (75Ω) can be configured with one transistor by

outputting the video output signal at 2VP-P.

•This device can be used for both NTSC system and PAL system.
