Abstract
An apparatus and method for serial link down detection are described. In one embodiment, the method includes the detection of an initial link down condition of a serial link. In one embodiment, the initial link down condition is detected, for example, when a transition from a normal signaling voltage level to a squelch signaling voltage level is detected at a receiver input. When an initial link down condition is detected, the issuance of a link down signal is delayed for a predetermined period of time from the detection of the squelch voltage over the serial link. In one embodiment, the link down signal is asserted if a data error is detected following the predetermined period of time from the detection of the squelch voltage. Other embodiments are described and claimed.
