datasheet loco? pll cloc k multiplier ICS511 idt? / ics? loco? pll clock multiplier 1 ICS511 rev k 051310 description the ICS511 loco tm is the most cost effective way to generate a high quality, high frequency clock output from a lower frequency crystal or clock input. the name loco stands for low cost oscillator, as it is designed to replace crystal oscilla tors in most electronic systems. using phase-locked loop (pll) techniques, the device uses a standard fundamental mode, inexpensive crystal to produce output clocks up to 200 mhz. stored in the chip?s rom is the ability to generate nine different multiplication fact ors, allowing one chip to output many common frequencies (see table on page 2). the device also has an output enable pin which tri-states the clock output when the oe pin is taken low. 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 skew, use the ics570b. features packaged as 8-pin soic or die pb (lead) free package upgrade of popular ics501 with: - changed multiplier table - faster operating frequencies - output duty cycle at vdd/2 zero ppm multip lication error input crystal frequency of 5 - 27 mhz input clock frequency of 2 - 50 mhz output clock frequencies up to 200 mhz extremely low jitter of 25 ps (one sigma) compatible with all popular cpus duty cycle of 45/55 up to 200 mhz mask option for nine selectable frequencies operating voltage of 3.3 v or 5 v tri-state output for board level testing industrial temperature version available advanced, low power cmos process block diagram clk pll clock multiplier circuitry and rom crystal or clock input gnd oe vdd crystal oscillator s1:0 x1/iclk x2 optional crystal capacitors 2
