Abstract
A method and apparatus in a receiver to determine if a high speed communication link is in an idle mode or in an active mode. Signals during the idle mode are of lower amplitude and lower frequency compared to amplitude and frequency in the active mode. A signal detector in the receiver determines if the high speed communication link has transitioned from idle mode to active mode and, if so, wakes up high power circuitry in the receiver to receive data.
