Disclosed is die-to-die (D2D) interconnect of a component die. In an aspect, the D2D interconnect includes a transmit selection circuit, a plurality of transmit gearboxes (Tx GBXs), and a plurality of transmit D2D physical layer interfaces. The transmit selection circuit may be configured to receive at least two traffic channels and to output a data stream of at least one traffic channel to the plurality of Tx GBXs. Each of a subset of Tx GBXs may be configured to receive at least a portion of the data stream from the transmit selection circuit and to output at least the portion of the data stream to a transmit D2D physical layer interface to which the Tx GBX is communicatively coupled. Each transmit D2D physical layer interface coupled to the subset of Tx GBXs may be configured to output at least the portion of the data stream.
