General Description
The ICS1527 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 ICS1527 is an
effective clock synthesizer that supports video
projectors and displays at resolutions from VGA to
beyond XGA.
The ICS1527 offers single-ended clock outputs to 60
or 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 either its internal
programmable feedback divider or an external divider.
The device is programmed by a standard I

serial interface and is available in a TSSOP16
package.
