LA7945規(guī)格書詳情
Overview
The LA7945N extracts the closed caption signal overlapped in the video signal vertical retrace period and transfers the data and clock signal to a decoder IC. This IC requires the use of either an add-on type decoder, such as the LC7458B or 7457A (for I2C), or a microcontroller type decoder, such as the LC8640XX.
Features
? Adoption of a dual loop AFC allows the LA7945N to stably extract the caption signal.
? Provides the pulse outputs required by caption decoder ICs.
Functions
? Synchronization separation.
? VCO
? Vertical countdown.
? Horizontal countdown.
? Data slicing.
? Dual loop AFC.
? Field discrimination.
? Lock detection
? Vertical/horizontal pulse output.
