Renesas Broadens its FemtoClock Timing Portfolio

Renesas Electronics has broadened its timing solutions portfolio with a new sub-100fs point-of-use clock solution for data center, server, and network infrastructure markets.

RenesasThe new FemtoClock2 family includes ultra-low jitter clock generators and jitter attenuators in a small 4×4 mm2 package, enabling cost-effective and simple clock tree implementation for next-generation, high-speed interconnect designs.

“PAM4 technology is enabling a major leap in data transmission rates in both communications and data center segments resulting in stringent requirement on the clock in such systems,” said Bobby Matinpour, Vice President of Timing Products, Data Center Business Division at Renesas. “Expanding our popular FemtoClock lineup, Renesas offers a new high-performance family that delivers superior jitter performance with low power in a small form factor, enabling placement of the clock anywhere on the board at the point of use. This greatly simplifies the design by eliminating the additive jitter associated with the extensive clock routing on the board.”

Featuring best-in-class jitter as low as 64fs RMS, FemtoClock2 enables customers to easily meet next-generation PAM4 requirements on new switch or router designs. With a 4×4 mm2 form factor, the FemtoClock2 family is less than one-third the size of similar solutions on the market.

This allows designers to place the clock source at the point of use – very close to the device receiving the clock signal – for streamlined PCB layout design, reduced cross talk, and cleaner signals. Flexibility makes the family useful in many applications. FemtoClock2 can be configured as a DCO, clock generator, or jitter attenuator, offering valuable design flexibility and reuse.

Customers can combine the new FemtoClock2 solution with Renesas’ small, single-output, high-performance oscillators, or the broader ClockMatrix portfolio of timing solutions to address challenging timing needs for their high-performance server and network infrastructure designs.

FemtoClock2 also works seamlessly with systems using the recently introduced PTP Clock Manager software for IEEE 1588 support and can be combined with Renesas’ complementary power and microcontroller offerings to create comprehensive solutions for a variety of applications, such as the IEEE 1588 Winning Combination. FemtoClock2 also serves as the downstream clock capable of delivering 100fs at the pin without disrupting the synchronization.

As the market leader in silicon timing, Renesas offers the only “one-stop-shop” for timing solutions, offering expertise and products from full-featured system solutions to simple clock tree building-block devices.
