SNLS614A September 2018 – December 2018 DP83869HM
The Auto-Negotiation function provides a mechanism for exchanging configuration information between the two ends of a link segment. This mechanism is implemented by exchanging Fast Link Pulses (FLP). FLPs are burst pulses that provide the signaling used to communicate the abilities between two devices at each end of a link segment. For further details regarding Auto-Negotiation, refer to Clause 28 of the IEEE 802.3 specification. The DP83869HM supports 1000BASE-T, 100BASE-TX, and 1000BASE-T modes of operation. The process of Auto-Negotiation ensures that the highest performance protocol is selected (that is, priority resolution) based on the advertised abilities of the Link Partner and the local device.
