LVCMOS User Configurable Clock
PRELIMINARY INFORMATION
Description
The ICS525-07/08 are the most flexible way to
generate a high-quality clock output from an
inexpensive crystal or clock input at low supply
voltages. The user can configure the device to produce
nearly any output frequency from any input frequency
by grounding or floating the select pins or by driving or
hard wiring the select pins high or low. 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.
For similar capability with a serial interface, use the
ICS307.
This product is intended for clock generation. It has low
output jitter (variation in the output period), but input to
output skew is not defined nor guaranteed.
