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’ VersaClock
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.
