Field Programmable Dual Output SS VersaClock Synthesizer
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.
Features
8-pin SOIC package

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
