San Jose, Calif.IDT (Integrated Device Technology Inc.) has started to sample the newest members of its VersaClock family of timing devices.
VersaClock III devices are programmable clock generators specifically designed for use in high-performance consumer, telecommunications, networking and data communications applications and are more versatile alternatives to using multiple crystals and oscillators. They are capable of reducing board space and maintaining power efficiency where volumes may not allow full custom solutions. Multiple systems, with widely varying requirements, can consolidate to fewer of these programmable devices improving inventory management.
The IDT VersaClock III family features four internal PLLs, each individually programmable and able to generate four unique frequencies. In addition, EMI-reducing spread spectrum technology is available on two of the PLLs, ensuring highest possible signal integrity. For even greater integration, VCXO versions are available to ensure IDT customers receive compatibility with industry timing standards.
The timing devices also feature an I²C interface, providing programmability during normal operation. The internal EEPROM allows the user to save and restore configuration of the device without having to reprogram it on power up, saving valuable design time and maximizing ROI. Moreover, to give designers even greater options, the new VersaClock devices can generate frequencies from 5kHz to 500MHz and are also compatible with many different output typesfrom single-ended LVCMOS to differential LVDS, LVPECL and HCSLto support all timing systems in a single device.
The VersaClock III devices feature lower jitter and clock redundancy, with a glitchless automatic or manual switchover function that allows the use of a secondary clock source to be selected if a clock error occurs during normal operation of the primary source, helping improve timing and device performance.
The VersaClock devices are available in several packages, including 28-pin TSSOP and 32-pin VFQFPN packages.
Pricing: Ranges from $1.75 to $3.20 for 10,000 units.
Availability: Sampling to qualified customers; evaluation boards are available for qualified customers.
