CS8900A
Crystal LAN™ Ethernet Controller
Active-high output used to select the EEPROM.
Serial input used to receive data from the EEPROM. Connects to the DO pin on the
EEPROM. EEDataIn is also used to sense the presence of the EEPROM.
Bi-directional signal used to configure external Latchable Address (LA) decode logic. If
external LA decode logic is not needed, ELCS should be tied low.
Serial output used to send data to the EEPROM. Connects to the DI pin on the
EEPROM. When TEST is low, this pin becomes the output for the Boundary Scan
Test.
Active-low output used to select an external Boot PROM when the CS8900A decodes
a valid Boot PROM memory address.
Differential output pair drives 10 Mb/s Manchester-encoded data to the 10BASE-T
transmit pair.
Differential input pair receives 10 Mb/s Manchester-encoded data from the 10BASE-T
receive pair.
Differential output pair drives 10 Mb/s Manchester-encoded data to the AUI transmit
pair.
Differential input pair receives 10 Mb/s Manchester-encoded data from the AUI receive
pair.
Differential input pair connects to the AUI collision pair. A collision is indicated by the
presence of a 10 MHz ± 15% signal with duty cycle no worse than 60/40.
