Quad 10G AES-256 MACSec LRM PHY

Currently Viewing:

The Broadcom BCM82756 is a low-power, high-density PHY that integrates IEEE 802.1AE MACsec GCM-AES-256b encryption, IEEE 1588, retimer and EDC equalizer functions supporting 40GbE, 10GbE and 1GbE applications. The BCM82756 is targeted for SMF, MMF, or copper twin-axial applications interfacing to both limiting-based and linear-based SFP+, SFP and QSFP+ modules.



  • Quad 10GbE port with SFI-to-XFI
    PHY supports SR/LR/CR/LRM,
    SFP+, retimer/equalization/MACsec
  • Supports IEEE 1588 timestamping
    as well as ITU-T Y.1731 with
    Synchronous Ethernet (SyncE)
    recovered clock outputs
  • Supports SFP+ SR, LR, and LRM
    optical interfaces, direct attach copper
  • Supports LRM/EDC - 300m of MMF,
    exceeding the IEEE 802.3aq
  • 1GbE mode with support for IEEE
    802.3 Clause 37 AN
  • Supports IEEE 802.3ap Clause 72
    transmit training
  • Supports 10G CL74 and 1G CL37
  • Integrated AC-coupling capacitors



  • MACsec encryption on high-density 1G/10G/40G front panel  LineCcards
  • Support SMF and MMF applications
