Establishing Link
Figure 6
shows an overview of link establishment for the LXT972M Transceiver.
Note:
When a link is established by parallel detection, the LXT972M Transceiver sets the duplex mode to
half-duplex, as defined by the IEEE 802.3 standard.
5.5.1
Auto-Negotiation
If not configured for forced operation, the LXT972M Transceiver attempts to auto-negotiate with
its link partner by sending Fast Link Pulse (FLP) bursts. Each burst consists of up to 33 link pulses
spaced 62.5
μ
s apart. Odd link pulses (clock pulses) are always present. Even link pulses (data
pulses) may be absent or present to indicate a ‘0’ or a ‘1’. Each FLP burst exchanges 16 bits of
data, which are referred to as a “link code word”. All devices that support auto-negotiation must
implement the “Base Page” defined by the IEEE 802.3 standard (Registers 4 and 5).
The LXT972M Transceiver also supports the optional “Next Page” function as listed in
Table 48,
“Auto-Negotiation Next Page Transmit Register - Address 7, Hex 7” on page 82
and
Table 49,
“Auto-Negotiation Link Partner Next Page Receive Register - Address 8, Hex 8” on page 82
.
5.5.1.1
Base Page Exchange
By exchanging Base Pages, the LXT972M Transceiver and its link partner communicate their
capabilities to each other. Both sides must receive at least three consecutive identical base pages for
negotiation to continue. Each side identifies the highest common capabilities that both sides
support, and each side configures itself accordingly.
