DM9301FP  
100Mbps Ethernet Fiber/Twisted Pair Single Chip Media Converter  
General Description  
The DM9301FP 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).  
recovery circuits to minimize bit delay through the  
converter (no FIFO is 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 DM9301FP needs no external filter  
to transport signals to the media on the 100Base-TX  
interface.  
The DM9301FP uses a low power and high  
Patent-Pending Circuits  
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 DM9301FP provides two independent clock
