Renesas Electronics RC223x FemtoClock™ Clock Synthesizers

Renesas Electronics RC223x FemtoClock™ Clock Synthesizers offer precision with jitter levels below 60fs (ttypicalp) using IOD and 120fs (typical) with FOD. The Renesas Electronics RC223x has a frequency range of 12kHz to 20MHz. With low power dissipation, the device operates at less than 1.2W in full configuration. The synthesizer has up to four independent frequency domains, enabling it to function as both a clock generator and a jitter attenuator. The RC223x complies with ITU-T G.8262 standards for SyncE/OTN (EEC/OEC) and ITU-T G.8262.1 for SyncE/OTN (eEEC/eOEC), ensuring reliable synchronization for various applications.
