Peripheral Circuit for TV/VCR Frequency Synthesizer Channel Select System

SANYO -> Panasonic 

Ordering number:ENN4038

Monolithic Linear IC

LA7916

Peripheral Circuit for TV/VCR Frequency

Synthesizer Channel Select System

Overview

The LA7916 contains CPU/PLL-excluded peripheral cir-

cuits such as switch, +5V power supply (with RST), sync

detector, low-pass filter for color TV/VCR frequency syn-

thesizer channel select system use.

Functions

• Band switch (2-input 4-output).

• Video signal, flyback pulse, AFT output-used detection

of tuning mode and horizontal sync mode.

• +5V power supply, with RST ouput (for CPU).

• Operational amplifier for low-pass filter (for frequency

synthesizer).

period of time at the user’s option.

• The band switch is of pnp output type which need not be

driven externally.

• The operational amplifier for low-pass filter is excellent

in pulse response because of its high-impedance input

pin.
