General Description

Features

•

Serial programming: Feedback and reference divisors,

The ICS1522 is a very high performance monolithic phase-

locked loop (PLL) frequency synthesizer. Utilizing ICS’s

advanced CMOS mixed-mode technology, the ICS1522

provides a low-cost solution for high-end video clock

generation where synchronization to an external video

source is required.

VCO gain, phase comparator gain, relative phase and

test modes.

•

Supports high-resolution graphics - Differential CLK

out-puts to 230 MHz

Eliminates need for multiple ECL output voltage control-

led crystal oscillators and external components

The ICS1522 has differential video clock outputs (CLK+

and CLK-) that are compatible with industry standard

video DAC.

Fully-programmable synthesizer capability - not just a

clock multiplier

Line-locked clock generation capability;

15 - 100 kHz

Operating frequencies are fully programmable with direct

control provided for reference divider, feedback divider

and postscaler.

•

External feedback loop capability allows graphics

system to be used as the feedback divisor with

synchronous switchover to internal feedback

•

Small footprint 24-pin SOIC

Coarse and fine phase adjustment permits precise

clocking in video recovery application

Applications

•

LCD Projector Systems

Multimedia video line locking

Genlock applications
