CS8900A

Crystal LAN™ Ethernet Controller

CIRRUS LOGIC PRODUCT DATASHEET

high level of integration allow System Engi-

neers to design a complete Ethernet circuit

that occupies as little as 1.5 square inches of

PCB area (Figure 1). In addition, the

CS8900A’s power-saving features and CMOS

design make it a perfect fit for power-sensitive

portable and desktop PCs. Motherboard de-

sign options include:

•

An EEPROM can be used to store node-

specific information, such as the Ethernet

Individual Address and node configuration.

•

The 20 MHz crystal oscillator may be re-

placed by a 20 MHz clock signal.

1.2.2 Ethernet Adapter Cards

The CS8900A’s highly efficient PacketPage

architecture, 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 configuration options and perfor-

mance features allow engineers to design

Ethernet solutions that meet their particular

system requirements. Adapter card design op-

tions include:

•

A Boot PROM can be added to support

diskless applications.

•

The 10BASE-T transmitter and receiver

impedance can be adjusted to support 100,

120, or 150 Ohm twisted pair cables.

•

An external Latchable-Address-bus de-

code circuit can be added to operate the

CS8900A in Upper-Memory space.
