SERIALLY PROGRAMMABLE CLOCK SOURCE
IDT™ / ICS™ SERIALLY PROGRAMMABLE CLOCK SOURCE
Description
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.
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.
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.
