• Manufacturer Part Number: max2986cxv
• Description: Integrated Powerline Digital Transceiver Integrated Products
• Manufacturer: Maxim Integrated Products, Inc.

The interface to the MAX2980 AFE chip uses a bidirec-
tional bus to pass the digital data to and from the DAC
and ADC. Handshake lines help accomplish the data
transfer as well as operation of the AFE. Figure 22
shows the interface signals. For AFE pin configuration/
description, refer to the MAX2980 data sheet.
Table 14. Disabling MII/RMII/FIFO Interface
Table 15. Disabling UART
Note: Disabling the UART interface disables the MAC code update and FLASH programming features of the chip.
