Microchip TimeCesium 4500


PRS-4400 and PRS-4500

The autonomous Microchip TimeCesium PRSs are based on the latest cesium III technology. They are designed to generate superior and highly reliable synchronization signals for advanced network services that meet the G.811 and G.811.1 standards. The TimeCesium PRS produces accurate, spectrally pure and stable output signals using a cesium beam tube resonator. It delivers total control of your 5G network synchronization source, enhances network performance, reduces errors in the SONET/SDH payload and prevents upstream network clock errors from propagating across the network.



Network Applications

The Microchip TimeCesium 4500 is used to equip core network offices with Stratum 1 synchronization.

The deployment of sources across the network provides the following benefits:

• Flattens the sync distribution hierarchy
• Lowers the overall OAM&P (Operation,
Administration, Maintenance &
Provisioning) costs
• Reduces the number of network recovery
clocks (TSG/SSU) operating in tandem
• Minimizes pointer adjustments caused by
“frequency errors” in the SONET/SDH
• Prevents up-stream network clock errors
from propagating across the network
• Enhances overall network performance
• Provides total control of network synchronization source

Standards Compliance

The 4500 meets industry standards, including ITU-T, ETSI, ANSI, Telcordia, NEBS, and CE/AS.
