ADVANCE INFORMATION

ICS548-03

Low Skew Clock Inverter and Divider

Description

Features

The ICS548-03 is a low cost, low skew, high

performance general-purpose clock designed to

produce a set of one output clock, one inverted

output clock, and one clock divided-by-2. Using

our patented analog Phase-Locked Loop (PLL)

techniques, the device operates from a frequency

range from 10 MHz to 120 MHz in the PLL mode,

and up to 160 MHz in the non-PLL mode.

In applications that to need maintain low phase

noise in the clock tree, the non-PLL (when

S3=S2=1) mode should be used.

• Packaged in 16 pin narrow (150 mil) SOIC

• Input clock up to 160 MHz in the non-PLL mode

• Provides clock outputs of CLK, CLK, and CLK/2

• Low skew (500 ps) on CLK, CLK, and CLK/2

• All outputs can be tri-stated

• Entire chip can be powered down by changing one

or two select pins

• 3.3V or 5.0V operating voltage

This chip is not a zero delay buffer. Many

applications may be able to use the ICS527 for zero

delay dividers.
