M61250BFP
NTSC 1 chip TV signal processor
REJ03F0088-0100Z
Rev.1.0
Sep.23.2003
Description
The M61250BFP is a single-chip semiconductor integrated circuit that contains the signal processing for NTSC color
television.
All of the signal processing circuits for video intermediate frequencies, vocal intermediate frequencies, video, color,
and polarization, as well as I2C bus control, are built in, and television sets ranging from popular-class to medium-grade
sets are supported. Moreover, the M37150 8-bit microcomputer for the television and the interconnection pin are
opposite each other, so that less space is required for mounting.
Features
• No VCO coil for VIF required
• Internal unregulated vocal demodulator
• PLL-SPLIT SIF system for FM radio
• Fsc output
• ACL or ABCL can be selected
• Internal horizontal oscillation probe
• Internal perpendicular sawtooth wave generator
• Internal self-diagnosis function
• Internal black peak hold, AFC2, killer filter
• H & V pulse output for OSD
• Internal reset circuit and clock output for microcomputer use
• Internal 5 V and 8 V regulators
Applications
• NTSC color television receivers
Recommended Operating Conditions
• Power supply voltage range:
4.75 V to 5.25 (Pins 3, 4, 39, 40)
7.6 V to 8.4 V (Pins 12, 44)
