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)
8.3 V to 9.1 V (Pin 42)
Recommended power supply voltage:
5.0 V (Pins 3, 4, 39, 40)
8.0 V (Pins 12, 44)
8.7 V (Pin 42)
