MDS 1526 L
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 IDT’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 110
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
standard I
a TSSOP16 package.
