Renesas delivers second-generation of ClockMatrix family

Renesas has introduced the ClockMatrix 2 high-performance, precision, multi-channel timing devices for 400/800Gbps optical transport and wireline network applications.

This second-generation family delivers improved performance with phase jitter as low as 88fs-rms.

Highly integrated these devices provide all the functionality needed to implement an IEEE1588 clock solution with jitter attenuation capabilities resulting in ultra-low jitter clock outputs for Synchronous Ethernet PHYs with data rates up to 112Gbps PAM-4, reducing design complexity and bill of materials (BOM) requirements, while also allowing customers to apply the timing devices to a wide variety of network applications.

Key Features of the ClockMatrix 2 Family

  • Highly integrated, 6-channel precision timing source that eliminates the need for additional jitter attenuators for high-speed interfaces
  • 88fs-rms phase jitter on clock outputs to support ultra-low jitter clock outputs for high-speed serial links (up to 112Gbps PAM-4 PHYs)
  • Supports multiple standards and protocols including synchronous Ethernet (Sync-E), and IEEE1588
  • Adherence to G.8262.1 and G.8262 telecom boundary clock requirements and G.8273.2 Class C and Class D time accuracy

The ClockMatrix 2 system synchronizer can be combined with Renesas’ complementary analogue and power offerings to create comprehensive solutions for a variety of applications.
