Epak 100G_ZX


1G-100G Ethernet/FiberChannel/FlexO Core

The 1G-100G Multi-channel Multi-rate Ethernet/FiberChannel/FlexO Core (Epak100G_ZX) core from Precise-ITC is a multi-rate Ethernet aggregator that supports tributaries at 1GE, 10GE, 25GE, 40GE, 50GE, 100GE in combinations up to 100G for Epak100G_ZX.

This core implements multi-rate Ethernet PCS and MAC. This versatile device allows users to add or drop sub-channels (for example 10GE) or merge channels (for example 4x25G = 100GE). These dynamic changes do not affect traffic on existing channels.

The north-bound interface from the multi-channel MAC provides a configurable system interface. The Multi-channel MAC manages the mapping between individual MACs and the assigned I/O or I/O group.

The southbound interface is mapped (at the PMA layer) to the on-chip SERDES. The core is responsible for channel alignment and FEC (where applicable).


  • Combines Ethernet streams at a variety of rates to a single multi-channel interface at the MAC
  • The Epak100G_ZX allows access connections supporting 1GE, 10GE, 25GE, 40GE, 50GE and 100GE in any combination on any port or groups of ports to a maximum total bandwidth of 100Gbps
  • Dynamically change rate on any port without affecting existing traffic
  • Off-the-shelf, proven technology implementation in ASIC SOC
  • Tested and interoperability-proven against Spirent and Viavi test equipment


  • Support any ethernet combinations (table 1) to maximum data-rate of the device
  • Fully compatible with IEEE802.3 2018 and IEEE 802.3 Standards
  • Support all IEEE802.3 PCS, FEC, and MAC statistics and alarms, and more
  • Optional add-on of ultra Low latency and area efficient FEC Core supports FC FEC RS (2112, 20280)

High-Speed Communication Cores

All Precise-ITC cores have been tested on both Intel/Altera and Xilinx FPGA hardware. Precise-ITC partners with leading test equipment vendors like Spirent and Viavi to prove interoperability. SOC cores have been implemented with ASIC/FPGA partners using the latest technology nodes.v

Precise-ITC cores are designed for efficiency. Built-in data buffers are efficiently implemented to reduce overall delay through the data path. Variable delay (or jitter) is tightly managed to ensure 1588v2 time-stamp accuracy. Precise-ITC can provide simulation models and routable RTL along with detailed interface documentation.
