ICS525R-07

www.DataSheet4U.com PRELIMINARY INFORMATION ICS525-07/08 LVCMOS User Configurable Clock 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. Features Packaged as 28-pin SSOP (150 mil body) Available in Pb (lead) free package User determines the output frequency by setting all internal dividers Eliminates need for custom oscillators Low voltage operation Pull-ups on all select inputs Input crystal frequency of 5 - 27 MHz Input clock frequency of 2 - 50 MHz Compensated loop bandwidth Enhanced low frequency operation (-08 version) Low jitter Duty cycle of 45/55 up to 200 MHz Opera...
