VersaClock® 3S Programmable Clock Generators

Renesas introduces its VersaClock 3S programmable clock generators. 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
