The PM5420 HyPHY-20G device is a feature-rich, high-capacity system-on-a-chip solution that enables universal multi-rate, multi-service 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 directconnect to SFPs and from 8.5 Gbit/s to 11.32 Gbit/s fordirect 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 jitterperformance when transporting clients over OTN
• OTN Payload Tributary Mapping (OPTM): low-order mapping into OPU1
• Constant Bit Rate Interface (CBRI): carry ODUks acrosssystem fabrics

The HyPHY-20G family includes a hardware & software compatible lower capacity variant PM5426 HyPHY-10G.
