M52390FP
Description
The M52390FP is a single-chip semiconductor integrated circuit which has a function to convert R/G/B signal to NTSC/PAL posite video signal and the superimpose function.
Key Features
- 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 (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. CLAMP R 4 5 6 7 8 9 M52390FP VIDEO OUT 10 Outline 20P2N-A (Lead pitch:1.27mm)
