The IDT6V40277 is a small, versatile serially programmable clock source for Freescale systems. 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 IDT6V40277 features a default clock output at start-up. 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.
