General Description
The DP83907 Twisted-Pair Enhanced Coaxial Network In-
terface Controller is a CMOS VLSI device designed for easy
implementation of CSMA CD local area networks
Unique to the DP83907 is the integration of the entire bus
interface for PCAT ISA (Industry Standard Architecture) bus
based systems Hardware and software selectable options
allow the DP83907鈥檚 bus interface to be configured in the
same manner as an NE2000 Architecture All bus drivers
and control logic are integrated to reduce board cost and
area
Supported network interfaces include 10BASE5 or
10BASE2 Ethernet via an external transceiver connected to
its AUl port and Twisted-pair Ethernet (10BASE-T) using
the on-board transceiver The DP83907 provides the Ether-
net Media Access Control (MAC) Encode-Decode (ENDEC)
with an AUl interface and 10BASE-T transceiver functions
in accordance with the lEEE 802 3 standards
The DP83907鈥檚 integrated 10BASE-T transceiver fully com-
plies with the IEEE standard This functional block incorpo-
rates the receiver transmitter collision heartbeat loop-
back jabber and link integrity blocks as defined in the stan-
dard The transceiver when combined with equalization re-
sistors transmit receive filters and pulse transformers pro-
vides a complete physical interface from the DP83907鈥檚
ENDEC module and the twisted pair medium
