Description
The ICS251 is a low cost, single-output, field programmable
clock synthesizer. The ICS251 can generate an output
frequency from 314 kHz to 200 MHz and may employ
Spread Spectrum techniques to reduce system
electro-magnetic interference (EMI).
Using IDT’s VersaClocksoftware to configure the PLL and
output, the ICS251 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 ICS251 is also available in factory programmed custom
versions for high-volume applications.
