IDT's New VersaClock 3S Clock Generators Deliver Innovative Features for Optimal Blend of Performance, Power and Flexibility

IDT VersaClock 3S

The Compact New Products Can Replace Multiple Crystals or Crystal Oscillators for a Smaller Board Footprint While Maintaining Extremely Low Power Consumption

Integrated Device Technology (IDT) introduced its VersaClock® 3S programmable clock generators, the newest members of its award-winning product line. The VersaClock 3S devices deliver innovative power-saving features while saving board space by eliminating the need for multiple discrete timing components. Delivering low power and low jitter scalability, the VersaClock 3S devices meet requirements for widely used standards including PCI Express® Gen 1/2/3 and are ideal for consumer, industrial, computing and automotive applications.

IDT - VersaClock 3S

The 5P35023 and 5P35021 chips deliver a unique set of features offering an optimal combination of performance, power and flexibility:

  • Proactive Power Saving – the world’s first intelligent timing device to detect power down status of the downstream clocked component, resulting in further energy savings in the system
  • Performance-Power Balancing – a user-friendly interface allowing users to easily minimize power consumption based on targeted performance
  • Dynamic Frequency Control – supported by one-time programmable (OTP) memory, this feature provides the system the ability to dynamically switch between up to four programmed frequencies, allowing optimized performance and power consumption
  • Overshoot Reduction Technology – prevents unwanted frequency overshoot that can lead to system failures during fast frequency changes

The devices have an extremely low-power digitally controlled oscillator supplying the system with a 32.768 KHz clock that can be powered by a coin battery, making it ideal for handheld and battery-powered applications.

The VersaClock 3S 5P35023 has three single-ended LVCMOS outputs and two differential outputs that support LVPECL, LVDS, LP-HCSL, and single-ended LVCMOS. The 5P35021 has one single-ended LVCMOS output and two differential outputs. Both versions feature a low-power 32.768 KHz clock output with less than 2 μA current consumption for use as a system RTC reference clock.
