Palma Distributed Unit

2U Ice-Lake-SP (ICX-SP) Based

Designed for Edge computing services with a focus on 4G/5G DUs (Distributed Units), the Palma platform’s features a front panel IO for RU (Radio Unit) connectivity, together with Silicom Time Sync (STS) Technology, 5G L1 Acceleration, and Remote Management capabilities such as ZTP.

The Palma platform offers up to 32 cores per socket and higher performance per core than the previous generation.
It offers expanded memory bandwidth, with 16DIMMs per socket and PCIe-Gen 4.0 connectivity.

5G Distributed Unit DU

Palma’s I/O interface supports PTP (1588) and SyncE for Time Synchronization, with 1G/10G/25G and 100G connectivity as ordering options. Palma’s design also enables hosting of multiple eASIC / FPGA cards for service acceleration in both wireline and wireless deployments.
