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
