| DATASHEET FIELD PROGRAMMABLE DUAL OUTPUT SS VERSACLOCK SYNTHESIZER ICS342 The ICS342 is a low cost, dual-output, field programmable clock synthesizer. The ICS342 can generate two output frequencies from 250 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 ICS’ VersaClockTM software to configure the PLL and output, the ICS342 contains a One-Time Programmable OTP ROM to allow field programmability. Programming features include 2 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 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 ICS342 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 • Two ROM locations for frequency and spread selection • 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 • Advanced, low power CMOS process • For one output clock, use the ICS341. For three output clocks, see the ICS343. 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.

The 342M-XX, 342M-XXLF, 342MI-XX, and 342MI-XXLF are factory programmed versions of the 342MP, 342MPLF, 342MIP, and 342MIPLF. A unique “-XX” suffix is assigned by the factory for each custom configuration, and a separate data sheet is kept on file.
