ICS307
Serially Programmable Clock Source
MDS 307 D
Integrated Circuit Systems, Inc. 525 Race Street San Jose CA95126(408) 295-9800tel www.icst.com
1
Revision 042501
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
Very low jitter
Operating voltages of 3.0 to 5.5 V
25 mA drive capability at TTL levels
Industrial temperature available
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 roughly 50%) are guaranteed
if the output divider is not changed.
The devices include 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.
