SYNC SEPARATOR WITH VARIABLE FILTER

ZXFV401

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.

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 curcuit to clamp the blanking voltage to a fixed

level.

Operating Temperature Range

-40ЊC to 85ЊC Storage -65ЊC to +150ЊC

Operating Ambient Junction temperature TJMAX150ЊC**

**The thermal resistance from the semiconductor die to ambient is typically 120ЊC/W when the SO16 package is

mounted on a PCB in free air. The power dissipation of the device when loaded must be designed to keep the

device junction temperature below TJMAX.

*During power-up and power-down, these voltage ratings require that signals be applied only when the power

supply is connected.

ELECTRICAL CHARACTERISTICS

VCC = 4.75 TO 5.25, RSET = 681k, RFILT = 22k, RNOSIG = 82k, Tamb = 25ЊC unless otherwise stated.
