ICS525R-08LFT Datasheet PDF - Integrated Circuit Systems

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.
