NTSC/PAL TV SIGNAL PROCESSOR
M52770SP
MITSUBISHI ICs (TV)
DESCRIPTION
The M52770SP 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 I
2
C 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
I
2
C Bus control of various functions
Easy interfacing with SECAM decoder for multistandard
applications
Small amount of peripheral components
