Monolithic Linear IC
LA7672
Color TV Single-Chip Signal Processor for
NTSC Systems (PLL Detection)
Overview
The LA7672 is a single-chip IC for color TVs based on
the NTSC system with on-chip circuit for all VIF, SIF,
video, chroma and deflection signal processing.
Features
[VIF]
• PLL detection (high video and audio quality)
• High-gain VIF amplifier
• High speed AGC
• On-chip APC time constant switch
[SIF]
• Simultaneous sound IN/OUT
• Video/audio simultaneous muting, or audio-only muting
possible
[Audio-visual switch]
• Internal/external audio-visual switch (VCC = 9 V)
Delay line Video external, audio external Switch rating

• RGB linear up (– 6 dB input: 2 V to 5 V)
• Fast blanking (B input combined use)
[Chroma]
• On-chip ACC filter, On-chip killer filter, Killer-circuit
hysteresis operation
• On-chip carrier filter
[Video]
• Black enhancement
• On-chip delay line
• Wide band width (9 MHz): delay line short
• Duel rank on-chip differentiation circuit also available
for soft also
• S input supported (VCR application)
• Variable DC transmission volume available (externally
attached circuit adjustment)
[Deflection]
