• Manufacturer Part Number: AM79C973KCW
• Description: PCnet-FAST III Single-Chip 10/100 Mbps PCI Ethernet Controller with Integrated PHY
• Manufacturer: Advanced Micro Devices

SWITCHING CHARACTERISTICS: BUS INTERFACE (CONCLUDED)
Notes:
1. Not tested; parameter guaranteed by design characterization.
2. Parameter value is given for automatic EEPROM read operation. When EEPROM port (BCR19) is used to access the EE-
Analog I/O - PECL Mode
Notes:
1. Applies to RX+, RX-, SDI+, SDI- inputs only. Any voltage applied to these pins must not be below V
2. Tested for D
3. Applies to TX+,TX- outputs only. Measured with the load of 82 W to D
