Renesas RC38108
One-Channel ultra-low phase noise synchronizer and Jitter Attenuator with 8 outputs

FemtoClock 3 family with industry leading phase noise and jitter is now expanding to address wireless infrastructure, including 5G and 5G-A, with high level of integration that supports up to 3 synchronization domains and 4 frequency domains with low power dissipation. FemtoClock 3 for wireless supports multiple operating modes, including synchronization, jitter attenuation, and RF clock generation.
Key features
- < 40fs (typ) Jitter with IOD, 12kHz - 20MHz @ 2.5GHz output
- Up to 8 multi-mode output with programmable output swing and up to 2.5GHz
- Up to 4 independent freq domains with 4 inputs (supports fail safe), 8 outputs
- Acts as clock generator or jitter attenuator
- Low power dissipation with < 1.2W in full config
- Enables SyncE+PTP synchronization and jitter attenuation in single device
- Compliant with ITU-T G.8273.2 T-BC for IEEE1588/SyncE, G.8262 for SyncE/OTN (EEC/OEC) & ITU-T G.8262.1 for enhanced SyncE/OTN (eEEC/eOEC)
Applications
