NTSC/PAL TV SIGNAL PROCESSOR M52770ASP MITSUBISHI ICs (TV)
DESCRIPTION
The M52770ASP is a single chip CTV processor which has VIF/SIF, luminance, chrominance, mono sound, OSD display, RGB interface, and deflection. And it is possible to control each parameters by I2C bus. A baseband 1H delay line is built-in, and conjunction with SECAM decoder M52325AP simplifies multi system CTV chassis.
FEATURES
- Built-in 1H Delay Line using Bi-CMOS technology
- Multistandard PLL demodulator for IF
- Alignment - free sound demodulator
- Flexible source selection with internal CVBS and external CVBS or Y/C input signal
- Audio switch integrated
- Integrated chroma trap and bandpass filters with auto-calibration
- Luminance delay line integrated
- RGB control circuit with cut-off and drive
- Linear RGB inputs and fast blanking
- Horizontal synchronaization with two control loops and alignment- free H-oscillator
- Vertical count-down circuit
- Vertical saw tooth generator integrated
- I2C Bus control of various functions
- Easy interfacing with SECAM decoder for multistandard
