ICS1527

Video Clock Synthesizer

General Description

Features

• Lead-free packaging (Pb-free)

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.

• Low jitter (typical 27 ps short term jitter)

• LVCMOS single-ended clock outputs

• 60/110 MHz speed grades available

• Uses 3.3 V power supply

• 5 Volt tolerant Inputs (HSYNC, VSYNC)

• Coast (ignore HSYNC) capability via VSYNC pin

• Industry standard I C-bus programming interface

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.

• PLL Lock detection via I C or LOCK output pin

• 16-pin TSSOP package

Applications

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.

• Frequency synthesis

• LCD monitors, video projectors and plasma displays

• Genlocking multiple video subsystems
