DATASHEET FIELD PROGRAMMABLE DUAL OUTPUT SS VERSACLOCK SYNTHESIZER ICS252 The ICS252 is a low cost, dual-output, field programmable clock synthesizer. The ICS252 can generate two output frequencies from 314 kHz to 200 MHz using up to two independently configurable PLLs. The outputs may employ Spread Spectrum techniques to reduce system electro-magnetic interference EMI . Using IDT’s VersaClock software to configure the PLL and output, the ICS252 contains a One-Time Programmable OTP ROM to allow field programmability. Programming features include 2 selectable configuration registers. The device employs Phase-Locked Loop PLL techniques to run from a standard fundamental mode, inexpensive crystal, or clock. It can replace multiple crystals and oscillators, saving board space and cost. The device also has a power-down feature that tri-states the clock outputs and turns off the PLLs when the PDTS pin is taken low. The ICS252 is also available in factory programmed custom versions for high-volume applications. • 8-pin SOIC package • Two addressable registers • Input crystal frequency of 5 to 27 MHz • Clock input frequency of 3 to 150 MHz • Output clock frequencies up to 200 MHz • Configurable Spread Spectrum Modulation • Operating voltage of V • Replaces multiple crystals and oscillators • Controllable output drive levels • Advanced, low-power CMOS process • Available in RoHS 5 green or RoHS 6 green and lead free compliant package Block Diagram X1 Crystal OTP ROM with PLL Values Crystal Oscillator External capacitors are required.
