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
