Abstract
A configurable multi-protocol transceiver implemented in an integrated circuit ('IC') includes configurable deskew circuitry. The transceiver has various configurable deskew settings to facilitate effectively adapting transmit and/or receive communications corresponding to a selected one of a plurality of high-speed communication protocols and/or adapt to different implementations in which a deskew block addresses either just static skew or both static and dynamic skew. Configurable circuitry is adapted to control an allowed data depth of a plurality of buffers. Configurable circuitry is adapted to control a deskew character transmit insertion frequency. A programmable state machine is adapted to control read and write pointers in accordance with selectable conditions for achieving an alignment lock condition. Configurable circuitry is adaptable to select between logic and routing resources in the transceiver and logic and routing resources in a core of the IC in which the transceiver is implemented for controlling at least certain deskew operations.
