Ti240 Transceiver Interface

The Ti240 high-speed transceiver interface is a multi-protocol, full duplex transceiver that supports data rates from 1.188 Gbps to 16 Gbps. It supports the PCIe 4.0, SGMII, and 10GBase-KR protocols, as well as a PMA Direct mode. You can use it in ×1, ×2, or ×4 configuration.

Note: All quads support SGMII, 10GBase-KR, and PMA Direct. All even quads support PCIe. All lanes must have the same link rate.
