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.
Features
Handling of VIF does not require a VCO coil
Adjustment-free audio demodulator
PLL-SPLIT SIF system with FM radio function
Supports component video-signal input
Fsc output available
ACL or ABCL is selectable
Built-in horizontal oscillator
Built-in sawtooth waveform generator for vertical sync
Self-diagnostic function
Built-in black-peak hold, AFC2, color killer filter
Horizontal / vertical pulse output for OSD
Built-in microcomputer reset circuit
Built-in microcomputer clock output
Built-in 5- and 8-V regulators
