Video precision sync separator


Posted on Mar 18, 2013

The GS4882 and GS4982 are precision sync separators for extracting timing information from NTSC, PAL, and SECAM video signals. The GS4882 generates noise immune and temperature stable composite sync, vertical sync, back porch and odd/even field signals. The GS4982 provides a horizontal sync output for those applications requiring horizontal sync extraction. The GS4882 and GS4982 feature an internal color burst filter for minimization of spurious timing information and the reduction of external component count.



The precision 50% sync slicing feature embodied in the device provides for superior sync extraction in the presence of noise and varying sync pulse amplitudes. The high performance dual mode input clamp aids in maintaining the accuracy of the internal
