General Description
the DM9162 not only connects the Medium
Access Control (MAC) layer, but the MII also
ensure a high inter-operability and flexibility with
different vendors. In media usage applications,
the DM9162 provides a direct interface either to
an Unshielded Twisted Pair Category 5 Cable
(UTP5) for 100BASE-TX Fast Ethernet, or an
UTP5/UTP3 Cable for 10BASE-T Ethernet.
The DM9162 contains the entire physical layer
functions of 100BASE-TX. Those physical layer
functions are defined by IEEE802.3u include the
Physical Coding Sub layer (PCS), Physical
Medium Attachment (PMA), Twisted Pair
Physical Medium Dependent Sub layer
(TP-PMD),
10BASE-TX
Encoder/Decoder
(ENC/DEC), and Twisted Pair Media Access
Unit (TPMAU).
DAVICOM’s DM9162 is a physical layer, low
power, and single-chip 10BASE-T/100BASE-TX
transceiver specifically designed for consumer
electronics,
industrial,
and
enterprise
applications. Through using a CMOS process,
the DM9162 has the advantage of ensuring both
high performance and savings in power
consumption.
Through utilization of automatic media speed
and protocol selection, the auto-negotiation
function is strongly supported in the DM9162.
Then due to the built-in wave shaping filter, the
DM9162 has a significant convenience of not
requiring an external filter to transport signals to
the media in 10BASE-T or 100BASE-TX during
Ethernet operation.
Through its Media Independent Interface (MII),
