tive portable and desktop PCs. Motherboard design gineers to design Ethernet solutions that meet their  
options include:  
particular system requirements. Adapter card de-  
sign options include:  
An EEPROM can be used to store node-specif-  
ic information, such as the Ethernet Individual  
Address and node configuration.  
A Boot PROM can be added to support diskless  
applications.  
The 20 MHz crystal oscillator may be replaced  
by a 20 MHz clock signal.  
The 10BASE-T transmitter and receiver im-  
pedance can be adjusted to support 100, 120, or  
150 Ohm twisted pair cables.  
1.2.2 Ethernet Adapter Cards  
An external Latchable-Address-bus decode cir-  
cuit can be added to operate the CS8900A in  
Upper-Memory space.  
The CS8900A’s highly efficient PacketPage archi-  
tecture, with StreamTransfer™ and Auto-Switch  
DMA options, make it an excellent choice for high-  
performance, low-cost ISA adapter cards  
(Figure 2). The CS8900A’s wide range of configu-  
ration options and performance features allow en-  
On-chip LED ports can be used for either op-  
tional LEDs, or as programmable outputs.
