Systems, apparatuses, and methods for implementing a deskewing method for a physical layer interface on a multi-chip module are disclosed. A circuit connected to a plurality of communication lanes trains each lane to synchronize a local clock of the lane with a corresponding global clock at a beginning of a timing window. Next, the circuit symbol rotates each lane by a single step responsive to determining that all of the plurality of lanes have an incorrect symbol alignment. Responsive to determining that some but not all of the plurality of lanes have a correct symbol alignment, the circuit symbol rotates lanes which have an incorrect symbol alignment by a single step. When the end of the timing window has been reached, the circuit symbol rotates lanes which have a correct symbol alignment and adjusts a phase of a corresponding global clock to compensate for missed symbol rotations.

Deskewing method for a physical layer interface on a multi-chip module

A transceiver apparatus includes a process, a first type of transceiver circuit for data transmission, a second type of transceiver circuit for data transmission, and a communications interface for communicating between the first type of transceiver circuit and an external device. The first type of transceiver circuit is co-located with a physical layer associated with the first type of transceiver circuit. In some embodiments, the first type of transceiver circuit can be, for example, a USB 2.0 transceiver circuit, and the second type of transceiver circuit can be a USB 3.0 transceiver circuit. The aforementioned external device can be an external USB device.
