NTSC/PAL TV SIGNAL PROCESSOR M52771ASP MITSUBISHI ICs (TV) PRELIMINARY Notice:This is not a final specification. Some parametric limits are subject to change.

DESCRIPTION

The M52771ASP 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 m ultistandard
