DATASHEET TRIPLE PLL FIELD PROG. SPREAD SPECTRUM CLOCK SYNTHESIZER ICS280 The ICS280 field programmable spread spectrum clock synthesizer generates up to four 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 IDT’s VersaClockTM software to configure PLLs and outputs, the ICS280 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 ICS280 is also available in factory programmed custom versions for high-volume applications. • Packaged as 16-pin TSSOP • Eight addressable registers • Replaces multiple crystals and oscillators • Output frequencies up to 200 MHz at V • Configurable Spread Spectrum Modulation • Input crystal frequency of 5 to 27 MHz • Input clock frequency of 3 to 166 MHz • Up to four reference outputs • Operating voltages of V • Controllable output drive levels • Advanced, low-power CMOS process • Available in RoHS compliant packaging NOTE EOL for non-green parts to occur on 5/13/10 per PDN U-09-01 Block Diagram 3 S2:S0 OTP ROM with PLL Values Crystal or Clock Input X1/ICLK Crystal Oscillator External capacitors are required with a crystal input.
