DM9301
100Mbps Ethernet Fiber/Twisted Pair Single Chip Media Converter
Final 1
Version: DM9301-DS-F02
May 8, 2000
General Description
The DM9301 is a physical-layer, single-chip, low-
power media converter for 100BASE-TX/FX full
duplex repeater applications. On the TX media side,
it provides a direct interface to Unshielded Twisted
Pair Cable 5 (UTP5) for 100BASE-TX Fast Ethernet.
On the FX media side, it provides a direct interface to
a Pseudo Emitter Coupled Logic level interface
(PECL).
The DM9301 uses a low power and high
performance CMOS process. It contains the entire
physical layer functions of 100BASE-TX as defined
by IEEE802.3u, including the Physical Coding
Sublayer (PCS), Physical Medium Attachment
(PMA), Twisted Pair Physical Medium Dependent
Sublayer (TP-PMD) and a PECL compliant interface
for a fiber optic module, compliant with ANSI X3.166.
The DM9301 provides two independent clock

recovery circuits to minimize bit delay through the
converter (no FIFO are used to buffer data between
the FX and TX interfaces). Furthermore, due to the
excellent rise/fall time control by a built-in wave-
shaping filter, the DM9301 needs no external filter to
transport signals to the media on the 100Base-TX
interface.
