TIME BASE CORRECTION DELAY LINE (TBC)
GENERAL DESCRIPTION
The SA07630 is a charge-coupled device (CCO) dual variable delay line. It is designed for fault correction
of composite video signals in compact disc video (COV) applications. One line can be used to correct
the time error of the composite video signal and the other line to correct the time error of the analogue
audio carriers.
Features
• Variable clock frequency range of 13 to 24 MHz
• Separate power supply (VOOA and VOOO) to prevent interference between digital and analogue
circuits
• Applicable for either PAL or NTSC players
