Ordering number : EN3804D
Monolithic Linear IC
LA7217
LA7217M
Synchronizing Signal Separator
with AFC and Sync Detector
Overview
The LA7217 and LA7217M 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, precision sync detection system.
Features
• Use of a ceramic oscillator requires no adjustment.
• Negative polarity output.
• High impedance video signal input pin.
• 5V supply voltage.
Functions
• Horizontal sync separation.
• Vertical sync separation.
• VCO (32fH).
• AFC.
• Sync signal detection.
