Ethernet Subsystem 10G/25G

Overview

Comcores Ethernet Subsystem IP is a silicon-agnostic, easy-to-use integration of specific IP blocks. The subsystem IP is richly featured, highly configurable and comes in different variations of Ethernet MAC, Ethernet PCS, IEEE 1588 PTP (with Time Stamping Unit), DMA and can include TSN features.

The subsystem IP is ready for 5G applications, and is thoroughly tested and verified, thus reducing your risks and will save development time as the solution will reduce your design and integration efforts.

Key Features

Flexible

The Ethernet subsystem consists of various IP blocks that can be selected or
deselected based on customers’ requirements. The main versions are:

01- Ethernet MAC and PCS
02- Ethernet MAC, PCS, and Timestamping Unit (TSU)
03- Ethernet MAC, PCS, and IEEE 1588 PTP (TSU and SW Stack)
04- Ethernet MAC, PCS, IEEE 1588 PTP (TSU and SW Stack), and DMA
*** Ethernet MAC can be replaced by TSN MAC in all versions

5G Ready

  • The subsystem has been designed for 5G applications and has been delivered to 5G projects.

Silicon Agnostic

  • Designed in VHDL and targeting both ASICs and FPGAs

Feature Rich

  • FCS generation supported
  • Deficit Idle Count for maximum data throughput supported
  • Jumbo frames support
  • Complete 10GBASE-R and 25GBASE-R PCS solution
  • Configurable for several operating modes and speeds
  • 64b 66b encoding/decoding
  • Reconciliation Sublayer (RS) and 10 Gigabit Media Independent Interface (XGMII)
  • Two-step messaging by default, with one-step messaging being optional

Ease-to-use and Reliable

  • HW validated subsystem
  • IP blocks are integrated and tested together
