Monolithic Linear IC

Peripheral Circuit for TV/VCR Frequency

Synthesizer Channel Select System

Ordering number:ENN4038

LA7916

SANYO Electric Co.,Ltd. Semiconductor Company

TOKYO OFFICE Tokyo Bldg., 1-10, 1 Chome, Ueno, Taito-ku, TOKYO, 110-8534 JAPAN

Overview

The LA7916 contains CPU/PLL-excluded peripheral cir­cuits such as switch, +5V power supply (with RST), sync
detector, low-pass filter for color TV/VCR frequency syn­thesizer 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).

Features

• The band switch truth table can be changed in a short
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.
