Overview

Product details

    The 1881 video sync separator extracts timing information (1) from standard negative sync NTSC, PAL to avoid composite and vertical synchronization, burst/back gallery timing, and parity field information, as well as SECAM video signals with a amplitude of 0.5V to 2V p-p. The integrated circuit is also capable of providing synchronous separation for non-standard, faster horizontal rate video signals. The vertical output is produced at the rising edge of the first sawtooth of the vertical synchronization cycle. If the above rising edge does not occur during the externally set delay period, a default vertical output is produced after the time delay, such as in the case of non-standard video signals.
