TSMC CLN28HPC+ Derivative IP of IGASERT06A Enterprise Multi-Standard SerDes

The GUC's Quad-Lane EMS-XT PHY SerDes supports multiple high speed wire-line communication standards. Supported standards include CEI-28G-VSR, CEI-25G-LR, 100GBase-KR4 (IEEE 802.3bj), CPRI, and analogous backplane or chip-to-chip standards. In addition, EMS-XT PHY mantains backward compatibility supporting common legacy data rates at 10.3125G, 6.25G, 3.125G, 1.25G, and similar data rates. The receiver equalizes and recovers incoming serial data and de-serializes the data stream into selectable 10/16/20/32/40/64 bit-wide data bus. The transmitter, similarly, serializes selectable 10/16/20/32/40/64 bit-wide data bus and drives the serialized data off-chip with built-in adjustable de-emphasis (FFE). EMS SerDes includes the physical media attachment layer (PMA) which is implemented as a hard macro and the physical coding sub-layer (PCS) which may be licensed separately through GUC or its 3rd party partners.
