Serially Programmable Clock Source

The 307-02 is a versatile serially programmable clock source which takes up very little board space. It 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 device includes a PDTS pin which tri-states the output clocks and powers down the entire chip. The 307-02 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 527-01.
