The PM5450 HyPHY 20Gflex device represents PMC-Sierra's 2nd generation of OTN-enabled, high-capacity system-on-a-chip solutions for Optical Transport Platforms (OTPs), Packet-OTPs, Metro Access Platforms, Wavelength Division Multiplexing (WDM) Platforms, Reconfigurable Optical Add-Drop Multiplexers (ROADMs), and Multi-Service Provisioning Platforms (MSPPs). The HyPHY 20Gflex brings ODU0 and ODUflex capabilities to universal multi-rate, multiservice line, transponder, and muxponder cards.
The HyPHY 20Gflex is pin-compatible to the PM5420 HyPHY 20G and delivers unprecedented single-chip scalability and feature integration to enable optimal footprint, power, and cost efficiency. The HyPHY 20Gflex provides a rich set of framing, mapping and multiplexing resources for a variety of protocols, including OTN, SONET/SDH, Ethernet, Fibre Channel, ESCON, FICON, and multi-rate bit transparent services such as video.
PMC’s new HyPHY Flex Reference Design enables OTN-based fronthaul networking in Centralized Baseband RAN (C-RAN) architectures. It includes software and firmware updates to the existing HyPHY SDK and firmware binary files, FPGA sample code, as well as application notes. With this reference design, existing HyPHY 20G/10Gflex designs can be easily upgraded for CPRI fronthaul support.
The HyPHY 20Gflex PM5450 offers the following innovations:
- True Any-Port, Any-Rate and Any-Service flexibility: Independent, rate-agile SERDES with integrated PLLs allows operation from a single reference, eliminating external timing components and significantly reducing cost, power and footprint.
- Carrier Ethernet transport: Transparent, semi-transparent and MAC-terminated transport of Ethernet, with onboard FE/GE and 10GE PCS/MACs, including support for Timing over Packet (IEEE 1588v2), Synchronous Ethernet (SyncE), and Ethernet Link OAM (IEEE 802.3ah).
- Field-proven interoperability with OIF OTN-over-packet-fabric standard: PMC’s OTN Phase Signaling Algorithm (OPSA™) and Constant Bit Rate Interface (CBRI™) technology provide an OIF-compliant and glueless interface to off-the-shelf or proprietary fabrics for fine-grain OTN switching.
- Integrated ODU0/ODUflex-granular framing, mapping, and switching: Up to 40G of OTN framing and 100G of OTN switching in a single chip, with the industry’s first on-board support for PTP (IEEE 1588v2) over OTN.
- Single-chip for DWDM muxponder and transponder, as well as OTN switching modes of operation.
- Comprehensive support for OTN fault restoration, resiliency and protection switching: Integration of supplementary OTN framers, monitoring and alarm insertion points to enable flexible protection switching schemes, such as Sub-Network Connection Protection (SNCP) for point-to-point, ring or mesh topologies.
- Flexible Interlaken and XAUI packet interface: Enables glueless interface to off-the-shelf network processors and Ethernet switches for implementation of hybrid multiservice OTN and Carrier Ethernet cards.
