The second generation of ClockMatrix devices from Renesas Electronics build on the earlier synchronisers and jitter attenuators released by the company for 5G wireless and 100/200Gbits per second wireline network applications. The ClockMatrix 2 family of high-performance, precision, multi-channel timing devices are intended for 400/800Gbits per second optical transport and wireline network applications. They also improve on performance with phase jitter as low as 88fs rms.
The integrated devices provide all the functionality needed to implement an IEEE1588 clock solution with jitter attenuation capabilities, says Renesas, resulting in low jitter clock outputs for synchronous Ethernet PHYs with data rates up to 112Gbps PAM-4. They are also claimed to reduce design complexity and bill of materials (BoM) requirements, while allowing customers to apply the timing devices to a wide variety of network applications.
The industry’s move to 5G is pushing the limits of network speed and precision and raising the bar on clock jitter and synchronisation capabilities, observed Bobby Matinpour, vice president of the Timing Products division at Renesas.
The integrated, six-channel precision timing source eliminates the need for additional jitter attenuators for high-speed interfaces. The 88fs-rms phase jitter on clock outputs supports low jitter clock outputs for high-speed serial links (up to 112Gbits per second PAM-4 PHYs). The ClockMatrix 2 also supports multiple standards and protocols including synchronous Ethernet (Sync-E), and IEEE1588 and adheres to G.8262.1 and G.8262 telecomms boundary clock requirements and G.8273.2 Class C and Class D time accuracy.
The RC32614A ClockMatrix 2 system synchroniser is available now. Optional PTP Clock Manager software is also available free of charge under license for use with the RC32614.
