ZXFV4583N16TC

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 for displays is facilitated by the Back Porch synch output, which can be used to drive an external circuit to clamp the blanking voltage to a fixed level. FEATURES AND BENEFITS PAL, NTSC, SECAM Variable filter for optimal accuracy Sync outputs: composite, horizontal, vertical, back porch, odd/even No-signal detector On chip sample / hold capacitors +5V single supply Default vertical output where there are no serration pulses Pin and layout compatible with part EL4583 in SO16N surface mount package APPLICATIONS Digital image capture Video input systems requiring separation of picture timing ORDERING INFORMATION Part Number ZXFV4583N16TA ZXFV4583N16TC Container Reel 7 ″ Reel 13 ″ Increment 500 2500 Video distribution CCTV surveillance Digital multimedia Timin...
