DEVICE DESCRIPTION

The ZXFV401 provides the ability to separate out video synchronisation signals for a wide variety of TV and CRT display systems, standard and non-standard.

Flexibility arises from the use of just three external resistors to adapt to each application. One resistor controls a fully integrated internal colour carrier filter with variable bandwidth. This filter aviods disturbance from the colour carrier, permitting accurate threshold slicing for timing extraction.
