DATASHEET TRIPLE PLL FIELD PROG. SPREAD SPECTRUM CLOCK SYNTHESIZER ICS290 The ICS290 field programmable spread spectrum clock synthesizer generates up to eight 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 ICS290 contains a One-Time Programmable OTP ROM for field programmability. Programming features include input/output frequencies, spread spectrum amount, eight selectable configuration registers and up to two sets of four low-skew outputs. 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 ICS290 is also available in factory programmed custom versions for high-volume applications. • Packaged as 20-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 • Clock input frequency of 3 to 166 MHz • Up to eight reference outputs • Up to two sets of four low-skew outputs • Operating voltages of V • Controllable output drive levels • Advanced, low-power CMOS process • Available in Pb lead free 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 X1/ICLK Crystal or Clock Input Crystal Oscillator External capacitors are required with a crystal input.
