The product family includes the industry’s first four-PLL-based PC clock device (CV115C) for these markets, enabling complete and independent control of key clock circuits within the system thereby resulting in increased flexibility and system performance. More specifically, the new IDT CV115C is the only product on the market to offer independent clocking for PCI Express, making it an appropriate fit for next-generation desktop PC platforms.

In addition to independent clocking for PCI Express, the IDT CV115C PC clock also offers independent clocking of CPU, SATA (Serial ATA) and USB interfaces, allowing each clock to be individually optimised within the system, resulting in superior performance.

A new VDD-suspend pin allows programming to be maintained in power-down mode, with power consumption less than 1mA.

The IDT CV115C architecture also incorporates programming that enables a linearly scalable frequency adjustment as opposed to the commonly used discrete stepping approach, allowing enthusiasts the ability to fine-tune their system for better performance.

In addition, with independent spread-spectrum control (SSC), each of the three SSC-capable PLLs within the device can be programmed independently to reduce EMI within the system.

“IDT has delivered a four PLL-based PC clock, offering features and benefits that complement the performance requirements of our next-generation Intel Desktop Boards”, said Mark Shipman, Director, Intel Desktop Board Operations.

“We are pleased to provide this new capability to our customers”.

IDT also unveiled a suite of three-PLL-based PC clocks (CV110J, CV123B) that are also targeted at the next-generation desktop PC market.
