2)-2. General Description
The RTL8019AS is a highly integrated Ethernet Controller which of-
fers a simple solution to implement a Plug and Play NE2000 compat-
ible adapter with full-duplex and power down features.
With the three level power down control features, the RTL8019AS is
made to be an ideal choice of the network device for a GREEN PC
system. The full-duplex function enables simultaneously transmission
and reception on the twisted-pair link to a full-duplex Ethernet switch-
ing hub. This feature not only increases the channel bandwidth from
10 to 20 Mbps but also avoids the performance degrading problem
due to the channel contention characteristics of the Ethernet
CSMA/CD protocol.
The RTL8019AS provides the auto-detect capability between the inte-
grated 10BaseT transceiver, BNC and AUI interface. Besides, the
10BaseT transceiver can automatically correct the polarity error on its
receiving pair.
The RTL8019AS is built in with 16K-byte SRAM in a single chip. It is
designed not only to provide more friendly functions but also to save
the effort of SRAM sourcing and inventory.
