IDT VersaClock® products are programmable devices that save cost, reduce board space and greatly increase versatility in consumer, data communications, telecommunications and networking applications.
VersaClock products allow designers to save board space and cost by replacing crystals, oscillators and buffers with a single timing device. VersaClock products are also an inexpensive and effective way to reduce EMI for FCC certification using IDT proprietary spread spectrum techniques. Exceptional versatility and configurability allow for maximum freedom in the design process.
IDT’s VersaClock product portfolio contains parts with up to four internal PLLs, each individually programmable, allowing for up to seven unique frequencies. Various subsets of the VersaClock family are targeted for different applications. For high-reliability systems, the VersaClock III family supports glitchless automatic or manual switchover function allows the redundant clock to be selected during normal operation.
For consumer systems, VersaClock III and LP provide flexibility with an internal EEPROM that makes it simple to reprogram frequencies for changing system requirements. The EEPROM also allows the user to save and restore the configuration of the device without having to reprogram it on power-up. For low powered battery applications, VersaClock LP has exceptionally low power consumption while maintaining high performance.
VersaClock devices are highly configurable and can be programmed through the use of the I2C interface. The programming interface enables the device to be programmed when it is in normal operation. The VersaClock Programmable product line has EEPROM, OTP and serial devices. These devices are ideal for larger opportunities that are still fluid and where there is a need to establish a board layout. The IDT VersaClock Programmable product line provides a competitive solution to your product needs and time-to-market requirements. VersaClock products from IDT provide an almost universal solution for a variety of high performance clock applications.

Software Requirements
This software calculates solutions for the VersaClock III family of programmable clocks. The configuration code generated by this software may be programmed through the I2C device port, enabling users to try out a variety of solutions with minimal turnaround time.
The VersaClock III devices do not need or have a programmer like the one used for the earlier parts. The parts may be programmed on the board through the I2C port in production.
Supported Platforms: 400 MHz Pentium II or later running Windows Vista, XP, 2000 and NT 4.0
Installation Requires: Microsoft Installer (MSI) Version 2.0. This is included with Windows Vista, XP and Windows 2000 SP3.
