DM9301F Product Brief  
100Mbps Ethernet Fiber/Twisted Pair Single Chip Media Converter  
June 2008 Rev.1.0  
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.
