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 ...
