Single-chip NTSC TV signal processor

www.DataSheet4U.com M61251AFP Single-chip NTSC TV signal processor REJ03F0078-0100Z Rev.1.0 Sep.22.2003 Description The M61251AFP is a single-chip TV-signal processor IC for the NTSC format and is ideal for use in combination with a microcomputer. Processing circuits for all signals, including intermediate-frequency video and audio, video, color, the on-screen display of characters, and the deflection system are all included, and various functions are controllable via an I2C bus. Furthermore, a reset circuit, clock circuit, and regulator are included for use with microcomputers.
