GS4911B Datasheet PDF (HD/SD/Graphics Clock and Timing Generator)

GS4911B - HD/SD/Graphics Clock and Timing Generator

Description

The GS4911B is a highly flexible, digitally controlled clock synthesis circuit and timing generator with genlock capability.

It can be used to generate video and audio clocks and timing signals, and allows multiple devices to be genlocked to an input reference.

Features

Video Clock Synthesis.
Generates any video or graphics clock up to 165MHz.
Pre-programmed for 8 video and 13 graphics clocks.
Accuracy of free-running clock frequency limited only by crystal reference.
One differential and two single-ended video/graphics clock outputs.
Each clock may be individually delayed for skew control.
Video output clock may be directly connected to Gennum’s serializers for a SMPTE-compliant HD-SDI output Audio Clock Sy.
