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 I 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.

2

C bus control, are built in, and television sets ranging from popular-class to medium-grade

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
