DATASHEET

SERIALLY PROGRAMMABLE CLOCK SOURCE

ICS307-01/-02

Description

Features

The ICS307-01 and ICS307-02 are versatile serially

programmable clock sources which take up very little

board space. They can generate any frequency from 6

to 200 MHz and have a second configurable output.

The outputs can be reprogrammed on the fly and will

lock to a new frequency in 10 ms or less. Smooth

transitions (in which the clock duty cycle remains near

50%) are guaranteed if the output divider is not

changed.

• Packaged in 16-pin (150 mil wide) SOIC

• ICS307M-02 and -02I available in Pb (lead) free

package

• Highly accurate frequency generation

• Serially programmable: user determines the output

frequency via a 3 wire interface

• Eliminates need for custom quartz

• Input crystal frequency of 5 - 27 MHz

• Output clock frequencies up to 200 MHz

• Power down tri-state mode

The devices includes a PDTS pin which tri-states the

output clocks and powers down the entire chip.

The ICS307-02 features a default clock output at

start-up and is recommended for all new designs.

• Very low jitter

• Operating voltage of 3.3 V or 5 V

• 25 mA drive capability at TTL levels

• Industrial temperature version available

NOTE: EOL for non-green parts to occur on 5/13/10

per PDN U-09-01

This product is intended for clock generation. It has low

output jitter (variation in the output period), but input to

output skew and jitter are not defined nor guaranteed.

For applications which require defined input to output

skew, use the ICS527-01.
