1 / 8 page ICS281 MDS 281 C 1 Revision 062205 Integrated Circuit Systems, Inc. ● 525 Race Street, San Jose, CA 95126 ● tel (408) 297-1201 ● www.icst.com Triple PLL Field Prog. Spread Spectrum Clock Synthesizer PRELIMINARY INFORMATION Description The ICS281 field programmable spread spectrum clock synthesizer generates up to three high-quality, high-frequency clock outputs including multiple reference clocks from a low-frequency crystal input. It is designed to replace crystals, crystal oscillators and stand alone spread spectrum devices in most electronic systems. Using ICS’ VersaClockTM software to configure PLLs and outputs, the ICS281 contains a One-Time Programmable (OTP) ROM for field programmability. Programming features include input/output frequencies, spread spectrum amount and eight selectable configuration registers. Using Phase-Locked Loop (PLL) techniques, the device runs from a standard fundamental mode, inexpensive crystal, or clock. It can replace multiple crystals and oscillators, saving board space and cost. The ICS281 is also available in factory programmed custom versions for high-volume applications. Features • Packaged as 16-pin TSSOP • Eight addressable registers • Replaces multiple crystals and oscillators • Output frequencies up to 200 MHz at 3.3 V • Configurable Spread Spectrum Modulation • Input crystal frequency of 5 to 27 MHz • Input clock frequency of 3 to 166 MHz • Up to three reference outputs • Operating voltages of 3.3 V • VDDO output control from 1.8 V to 3.3 V • Controllable output drive levels • Advanced, low-power CMOS process • Available in Pb (lead) free packaging Block Diagram Crystal Oscillator GND 3 3 VDD PDTS PLL2 PLL3 Divide Logic and Output Enable Control S2:S0 CLK1 CLK3 CLK2 3 OTP ROM with PLL Values X2 Crystal or clock input External capacitors are required with a crystal input.
