The ICS525-01 and ICS525-02 OSCaR are
the most flexible way to generate a high quality,
high accuracy, high frequency clock output from
an inexpensive crystal or clock input. The name
OSCaR stands for OSCillator Replacement, as
they are designed to replace crystal oscillators in
almost any electronic system. The user can easily
configure the device to produce nearly any
output frequency from any input frequency by
grounding or floating the select pins. Neither
microcontroller nor 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 LOCO family
of parts, which are smaller and more cost
effective.
