2. General Description
DAVICOM’s DM9163 is a industrial temperature SPI
to 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 DM9163 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 DM9163. Then due to the
built-in wave shaping filter, the DM9163 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), the

● Lower Power consumption modes:
Power Reduced mode (cable detection)
Power Down mode
● Single register access for complete PHY
status
● 10/100 Mb/s packet BIST (Built in Self
Test)
● 48-pin LQFP package (7mm) x (7mm)
DM9163 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 DM9163 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 DM9163 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).
