DATASHEET FIELD PROGRAMMABLE TRIPLE OUTPUT SS VERSACLOCK SYNTHESIZER ICS343 The ICS343 is a low cost, triple-output, field programmable clock synthesizer. The ICS343 can generate three output frequencies from 250 kHz to 200 MHz, using up to three independently configurable PLLs. The outputs may employ Spread Spectrum techniques to reduce system electro-magnetic interference EMI . Using ICS’ VersaClock software to configure the PLL and output, the ICS343 contains a One-Time Programmable OTP ROM to allow field programmability. 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 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 ICS343 is also available in factory-programmed custom versions for high-volume applications. • 8-pin SOIC package • Highly accurate frequency generation • M/N Multiplier PLL M = N = • Output clock frequencies up to 200 MHz • Spread spectrum capability for lower system EMI • Center or Down Spread up to 4% total • Selectable 32 kHz or 120 kHz modulation • Input crystal frequency from 5 to 27 MHz • Input clock frequency from 2 to 50 MHz • Operating voltage of V, using advanced, low power CMOS process • For one output clock, use the ICS341. For two output clocks, see the ICS342. For more than three outputs, see the ICS345 or ICS348. • 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 Crystal or clock input X1/ICLK OTP ROM with PLL Divider Values Crystal Oscillator External capacitors are required with a crystal input.
