ICS342 General Description
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.
