Abstract
A transceiver includes a first transmit (Tx) component configured to connect to a second receive (Rx) component in a second transceiver; a first Rx component configured to connect to a second Tx component in the second transceiver; a single Phase-Locked Loop (PLL) circuit connected to both the first Tx component and the first Rx component; and a control circuit configured to continuously calibrate a first Look-Up Table (LUT) configured to feed operating codes to a first phase rotator connected to an output of the single PLL circuit and to one of the first Tx component and the first Rx component. In an embodiment, the control circuit is further configured to continuously calibrate a second LUT configured to feed operating codes to a second phase rotator connected to an output of a single PLL circuit in the second transceiver.
