DATASHEET
FIELD PROGRAMMABLE DUAL OUTPUT SS VERSACLOCK SYNTHESIZER
ICS252
IDT / ICS FIELD PROGRAMMABLE DUAL OUTPUT SS VERSACLOCK SYNTHESIZER 1
ICS252
REV E 082007
Description
The ICS252 is a low cost, dual-output, field programmable
clock synthesizer. The ICS252 can generate two output
frequencies from 314 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 IDT’s VersaClocksoftware to configure the PLL and
output, the ICS252 contains a One-Time Programmable
(OTP) ROM to allow field programmability. Programming
features include 4 selectable configuration registers.
The device employs Phase-Locked Loop (PLL) techniques
to run 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 ICS252 is also available in factory programmed custom
versions for high-volume applications.
