The Renesas VersaClock® family of programmable clock generators offer a combination of low power consumption, flexibility and performance to simplify system design by replacing multiple discrete timing components and lower costs by reducing BOM and board space. These features offer greater versatility in consumer, data communications, telecommunications, and networking applications.

The VersaClock product family supports operating voltages from 1.8V to 3.3V, differential (LVPECL/HCSL/LVDS/LP-HCSL) and LVCMOS output types, up to 3 PLLs and multiple fractional dividers to accurately generate virtually any frequency. Products satisfy system requirements from oscillator replacement to PCIe® Gen 1/2/3 and to communications applications, while consuming very little power.

VersaClock 6E Key Features and Benefits

  • <500fs RMS phase jitter for stringent noise requirements
  • 30mA core current consumption
  • Any-in, any-out frequencies with 4 fractional dividers
  • No external memory needed – 4 configurations available in OTP
  • I2C programmable
  • PCIe Gen 1/2/3 standard-compliant

VersaClock 3S Key Features and Benefits

  • 2mA – 10mA – 15mA low power three-PLL design for easy power and performance trade-off
  • PCIe Gen 1/2/3 standard compliance
  • <2µA 32.768kHz RTC clock
  • I2C interface
  • Configurable OE pin function as OE, PD#, PPS or DFC control function

Various subsets of the VersaClock family are targeted for different applications, including VersaClock 5, VersaClock 6, and VersaClock 3S. For low-power, high-performance applications, VersaClock 5 provides 0.7ps phase jitter, and the ability to store up to four different frequency configurations in a single device. With RMS phase jitter less than 0.7 picoseconds over the full 12kHz to 20MHz integration range, VersaClock 5 meets the stringent jitter requirements of PCI Express Gen 1/2/3, USB 3.0, and 1G/10G Ethernet. The high-performance clock generator operates at less than 100mW core power (50 percent lower than competing devices), helping to ease system thermal constraints, reduce operating power expenses.

The VersaClock 6 programmable clock generator family delivers flexible, low-power timing for demanding high-performance applications. With RMS phase jitter of less than 500 femtoseconds (fs), the VersaClock 6 products deliver the best performance to date for Renesas' award-winning VersaClock family, offering an exceptional combination of jitter performance, flexibility, and low operating power. With RMS phase jitter less than 500fs over the full 12kHz to 20MHz integration range, the new devices meet the stringent jitter and phase noise requirements of such technologies as 10G Ethernet, PCI Express Gen 1/2/3, stringent PHY reference clocks and the newest generations of high-end FPGAs — all while operating at about half the core power of competing devices. The devices’ core current consumption of 30mA eases system thermal constraints and reduces operating power expenses. In addition, the VersaClock 6 devices are footprint compatible with their VersaClock 5 counterparts, enabling performance scalability with minimal design changes.

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 Renesas VersaClock programmable product line provides a competitive solution to your product needs and time-to-market requirements. VersaClock products from Renesas provide an almost universal solution for a variety of high-performance clock applications.
