M52770SP
NTSC/PAL TV SIGNAL PROCESSOR
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 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
applications
• Small amount of peripheral components
