The PM5450 HyPHY-20Gflex family of device represents Microchip’s 2nd generation of OTN-enabled, high-capacity system-on-a-chip solutions for Multi-Service Provisioning Platforms (MSPPs), Wavelength Division Multi-plexing (WDM) Platforms, Reconfigurable Optical Add-Drop Multiplexers (ROADMs), Optical Transport Platforms (OTPs), Packet-OTPs and Optical Access Platforms. 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.

The HyPHY-20Gflex is hardware and software compatible to the lower capacity variant PM5451 HyPHY-10Gflex.
