DM9331AE Product Brief
100 Mbps Twisted Pair/Fiber Ethernet Media Converter Chip
June 2008 Rev.1.0
converter application. On the media side, it provides a direct interface either to
Unshielded Twisted Pair Category 5 Cable 5 (UTP5) for 100BASE-TX Fast Ethernet,
and it also provides PECL interface to connect the external fiber optical transceiver.
Through the Media Converter Interface (MCI), the DM9331A connects to another
DM9331A for the twisted pair to the fiber media converter, or fiber to fiber repeater.
The DM9331A 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 optical module, compliant with ANSI X3.166. The DM9331A
provides a strong support for the auto-negotiation function, utilizing automatic
selection of full or half-duplex mode. Furthermore, due to the built-in wave-shaping
filter, the DM9331A needs no external filter to transport signals to the media on the
100base-TX Ethernet operation.
