Sanyo LA7217M Specifications

Ordering number:EN3804B

Monolithic Linear IC

LA7217, 7217M

Synchronizing Signal Separator

with AFC and Sync Detector

Overview

The LA7217 and 7217M are synchronizing signal
separator ICs with AFC and AFC Lock detector designed
to be used in video equipments such as VCR and TV sets.
VCO with ceramic oscillator and PLL horizontal sync
detector provide an adjust-free, percision sync detection

system.

Functions

• Horizontal sync separation.

• Vertical sync separation.

• VCO (32fH).

• AFC.

• Sync signal detection.

Features

• Use of a ceramic oscillator requiers no adjustment.

• Negative polarity output.

• High impedance video signal input pin.

• 5V supply voltage.
