Serial Management I/F
The high-speed Serial Management Interface (SMI) provides access to repeater MIB variables,
RMON Statistics attributes and status and control information. A network manager accesses the
interface through a simple serial communications controller such as an 8530 SCC. The SMI allows
multiple LXT98x0 devices to be managed from one common bus.
3.10.1
SMI Signals
The interface consists of a data input line (SRX), data output line (STX), and a clock (SERCLK).
The interface operates on a simple command response model, with the network manager as the
master and the LXT98x0 devices as slaves.
Figure 11
is a simplified view of typical serial
management interface architecture. Refer to
Figure 23 on page 68
for circuit details.
Note:
Refer to Application Note 64,
High-Speed Serial Management Interface,
for additional
information.

MAC
The two LXT98x0 MII ports act
as the PHY side of the MII. An
external MAC sends TX Data to
the LXT98x0 to be repeated to
the network. The LXT98x0
repeats network data to the MAC
via the RX Data lines.
