M61251AFP Datasheet | Renesas

Description The M61251AFP is a single-chip TV-signal processor IC for the NTSC format and is ideal for use in bination with a microputer. 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 microputers.
