MDS 525-01/02 T
Description
The ICS525-01/02 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 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 LOCO
are smaller and more cost effective.
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
timing, use the ICS527-01.
