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).
Benefits
- 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

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.
