General Description

The ICS1526 is a low-cost, high-performance

frequency generator. It is suited to general purpose

phase controlled clock synthesis as well as

line-locked and genlocked high-resolution video

applications. Using ICS’s advanced low-voltage

CMOS mixed-mode technology, the ICS1526 is an

effective clock synthesizer that supports video

projectors and displays at resolutions from VGA to

beyond XGA.

The ICS1526 offers single-ended clock outputs to 200

MHz. The HSYNC_out, and VSYNC_out pins provide

the regenerated versions of the HSYNC and VSYNC

inputs synchronous to the CLK output.

The advanced PLL uses its internal programmable

feedback divider. The device is programmed by a

a TSSOP16 package.
