DATASHEET TRIPLE PLL FIELD PROGRAMMABLE VCXO CLOCK SYNTHESIZER ICS275 The ICS275 field programmable VCXO 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 and crystal oscillators in most electronic systems. Using IDT’s VersaClockTM software to configure PLLs and outputs, the ICS275 contains a One-Time Programmable OTP ROM for field programmability. Programming features include VCXO, eight selectable configuration registers and up to two sets of two low-skew outputs. Using Phase-Locked Loop PLL techniques, the device runs from a standard fundamental mode, inexpensive crystal, or clock. It can replace VCXOs, multiple crystals and oscillators, saving board space and cost. The ICS275 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 • Input crystal frequency of 5 to 27 MHz • Up to four reference outputs • Up to two sets of two low-skew 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 S2:S0 3 OTP ROM with PLL Values X1 Crystal Voltage Controlled Crystal Oscillator External capacitors are required.
