DescriptionTRIPLE PLL FIELD PROGRAMM
The ICS271 field programmable VCXO clock synthesizer generates up to six high-quality, high-frequency clock outputs including multiple reference clocks from a low-frequency crystal input. 271PGI is designed to replace crystals and crystal oscillators inmost electronic systems.
Using the IDT VersaClock? software to configure PLLs and outputs, the ICS271 contains a One-Time Programmable (OTP) ROM for field programmability. Programming features include VCXO, eight selectable configuration registers and up to two sets of three low-skew outputs.
Each of the two output groups are powered by a separate VDDO voltage. VDDO may vary from 1.8 V to VDD. Using Phase-Locked Loop (PLL) techniques, 271PGI runs from a standard fundamental mode, inexpensive crystal, or clock. It can replace VCXOs, multiple crystals and oscillators, saving board space and cost.
The ICS271 is also available in factory programmed custom versions for high-volume applications.
