Programmable system-on-chip (SoC)
PMC Sierra

The PM5420 HyPHY 20G device is a feature-rich, high-capacity system-on-a-chip solution that enables universal multi-rate, multiservice line cards, transponder cards, and muxponder cards for Multi-Service Provisioning Platforms (MSPPs), Wavelength Division Multiplexing (WDM) Platforms, Reconfigurable Optical Add-Drop Multiplexers (ROADMs), Optical Transport Platforms (OTPs), Packet-OTPs, and Optical Access Platforms.

The HyPHY 20G delivers unprecedented single-chip scalability and feature integration to enable optimal footprint, power, and cost efficiency. The HyPHY 20G 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.

The HyPHY 20G introduces an array of innovative technologies:

Rate-Agile Programmable Transceiver IO (RAPTR IO): Gapless rate-agile SERDES from 16 Mbits to 5 Gbit/s for direct connect to SFPs and from 8.5 Gbit/s to 11.32 Gbit/s for direct connect to SFP+ (limiting) and XFP modules
Tri-FEC: Interoperable ITU-T G.709 and G.975.1 (I.4 and I.7) FEC
OTN Phase Signaling Algorithm (OPSA): Improve jitter performance when transporting clients over OTN
OTN Payload Tributary Mapping (OPTM): Low-order mapping into OPU1
Constant Bit Rate Interface (CBRI): Carry ODUks across system fabrics.
