User Configurable Clock
Description
The ICS525-01/02/11/12 are the most flexible way to
generate a high-quality, high-accuracy, high-frequency
clock output from an inexpensive crystal or clock input.
The user can configure the device to produce nearly
any output frequency from any input frequency by
grounding or floating the select pins. Neither
microcontroller, software, nor device programmer are
needed to set the frequency. Using Phase-Locked
Loop (PLL) techniques, the device accepts a standard
fundamental mode, inexpensive crystal to produce
output clocks up to 250 MHz. It can also produce a
highly accurate output clock from a given input clock,
keeping them frequency locked together.
For similar capability with a serial interface, use the
ICS307. For simple multipliers to produce common
frequencies, refer to the ICS50x family of parts, which
are smaller and more cost effective.
These products are intended for clock generation. They
have 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 timing, use the ICS527-01.
