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. FEATURES AND BENEFITS • PAL, NTSC, SECAM, other TV systems • Super accurate synch slice • Variable filter for outputs: composite, horizontal, Vertical, back porch, odd / even • No-signal detector • On chip sample / hold capacitors • +5V single supply • 4.5 mA supply current • Default vertical output where there are no serration pulses • Pin compatible with industry standard part SO16N surface mount package APPLICATIONS • Digital image capture • Video input systems requiring separation of picture timing • Video distribution • CCTV surveillance • Digital multimedia • Timing for black level clamp
