ICS307

Serially Programmable Clock Source

Description

Features

The ICS307-01 and ICS307-02 are versatile

serially programmable clock sources which take

up very little board space.

• Packaged as 16 pin narrow SOIC

• 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

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 roughly 50%) are guaranteed

if the output divider is not changed.

• Very low jitter

The devices include a PDTS pin which tri-states

the output clocks and powers down the entire

chip.

• Operating voltages of 3.0 to 5.5 V

• 25 mA drive capability at TTL levels

• Industrial temperature available

The ICS307-02 features a default clock output

at start-up and is recommended for all new

designs.
