VersaClock 3S Low Power Programmable Clock Generators by IDT


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.

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 32.768KHz clock that can be powered by a coin battery, making it ideal for handheld and battery-powered applications.
