Description

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).

Features

• 8-pin SOIC package (Pb-free)

• Highly accurate frequency generation

• M/N Multiplier PLL: M = 1...2048, N = 1...1024

• 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 3.3 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.
