56G SerDes
The Innosilicon 56G SerDes PHY is a highly configurable PHY
capable of supporting speeds up to 56Gbps within a single lane.
For this datasheet, the PHY has been configured to support 56G
PAM-4 and NRZ specifically, but the PHY itself can be configured
to support a wide range of HS SERDES protocols through changes to
the PCS layer and register settings.
