General Description

The GS1881, GS4881 and GS4981 are general purpose sync separators for use in a wide variety of video applications.

The devices extract the timing information from composite video signals with scan rates from 15 to 130kHz.

The GS1881 is a drop-in replacement for the industry standard LM1881 with much improved performance.

Key Features

  • noise tolerant odd/even flag, back porch and horizontal sync pulse.
  • fast recovery from impulse noise.
  • excellent temperature stability.
  • 0.5V to 4Vpp input signal amplitude with 5V supply.
  • well-controlled clamp discharge current and slicing level.
  • programmable horizontal scan rate (up to 130kHz).
  • composite, vertical, back porch, odd/even (GS1881, GS4881), horizontal (GS4981) outputs.
  • predictable vertical output pulse width wi.
