Abstract
Disclosed are apparatus and methods to advantageously manage transceiver power in an automated manner using adaptation logic that may be implemented on a same integrated circuit as the transceiver circuitry. In one embodiment, a power-consuming component of the transceiver is turned on at a lowest power setting. A determination is made as to whether a first set of eye opening data for a serial data signal meets preset criteria. If the preset criteria are not met by the first set of eye opening data, then the power-consuming component is changed to a second lowest power setting. Another embodiment relates to an integrated circuit including a receiver buffer, a receiver equalization circuit, an eye viewer circuit and adaptation logic. The adaptation logic is configured to obtain the eye opening data and to adapt the receiver equalization circuit to conserve power used. Other embodiments, aspects and features are also disclosed.
