ICS1527

Video Clock Synthesizer

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 I2C-bus™

serial interface and is available in a TSSOP16

package.
