Customer Remarks

“Nuvation has been a select member of our Certified Design Center program for several years, as well as a design services vendor to Altera. We have been consistently impressed with the caliber of their organization, the time-to-market acceleration that they enable, and their strong track record across our broad customer base.”
-- Altera

"Nuvation has been a long standing Xilinx XPERT partner and consistently delivers leading edge designs and rapid design cycles for our OEM customers.”
-- Xilinx

"Nuvation recently helped us to complete a complex design. The combination of Nuvations design experience with FPGA's and our engineering and design expertise with Analog-to-Digital Converters created a very useful test and characterization solution for one of our new series of data converters. It is fun working with Nuvation. They met all expectations."
-- Texas Instruments

Description

The GEOS-2 IP core multiplexes 2 channels of GE traffic into a single Packet over SONET (POS) stream, using frame-mapped GFP (Generic Framing Procedures). The GEOS-2 core is designed to interface with a Dual-Port Capable Gigabit Ethernet MAC (PMC-Sierra PM3386 S/UNI® - 2x1GE) and a 2.488Gbit/s SONET/SDH Framer Device (PMC-Sierra PM5381 S/UNI® 4x622), using POS-PHY Level 3 cores.


Features

  • Supports up to OC-48 bandwidth
  • Multiplexes 2 ports of Gigabit Ethernet traffic into SONET
  • Configurable destination port address
  • Complies with Frame Mapped Generic Framing Procedures from ITU-T
  • A Link Layer function
  • Provides GbE Traffic Statistics per port
  • Plug & Play with POS-PHY Level 3 cores for variety of system solutions with different bandwidths
  • Optimized for integration with a 2-Port Gigabit Ethernet MAC using POS-PHY Level 3 cores
  • Encrypted Netlist available
  • Available on Altera Cyclone EP1C20
