Renesas shipping low jitter 400/800Gps timing devices

Author: EIS Release Date: Dec 29, 2021

Renesas is shipping multi-channel timing devices for 400/800Gbps optical transport and wireline network applications with phase jitter as low as 88fs-rms.

 

The 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.

 

Features include:

 

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.
