Abstract: Various embodiments of methods and systems for closed loop multimode sleep clock frequency compensation in a portable computing device are disclosed. An exemplary embodiment leverages a modem to determine a frequency shift on a sleep clock signal when a reference clock has transitioned into a power saving mode. Using the frequency shift calculation, a compensation capacitor may be adjusted to deliver a more optimum dummy load on the crystal oscillator when the reference clock is taken offline. The method may iterate through until the actual frequency shift of the sleep clock is within an acceptable tolerance relative to zero and, further, may also set a status bit to indicate that the sleep clock frequency is stable.

Abstract: In high-speed link structures a receiver outputs a signal detect indicator (SDI) with a first logic value when transmissions are detected and a second logic value when suspension of transmissions is detected. A controller detects transitions in the SDI and causes corresponding transitions in an energy detect indicator (EDI). A physical control sublayer (PCS) has different operating states that cause the receiver to operate in different power modes and transitions between the operating states based on the EDI. If the EDI has the second logic value, the PCS remains in a non-active state and the receiver operates in a low power idle (LPI) mode. When the EDI transitions to the first logic value, the PCS exits the non-active state and the receiver operates in a non-LPI mode. To ensure that the PCS properly enters and doesn't pre-maturely exit the non-active state, EDI transitions to the first logic value are delayed.
