ZXFV4583 SYNC SEPARATOR WITH VARIABLE FILTER DEVICE DESCRIPTION The ZXFV4583 provides the ability to separate out video synchronization 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 color carrier filter with variable bandwidth. This filter avoids disturbance from the color carrier, permitting accurate threshold slicing for timing extraction. A second resistor controls the voltage threshold for loss of signal detection after a time-out interval. The third resistor controls the timing functions. DC restoration...
