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

The MAX2986 powerline transceiver IC is a state-of-the-
art CMOS device, which delivers high performance at
reduced cost. This highly integrated design combines
the MAC layer with the PHY layer in a single chipset.
The MAX2986 and the companion device, the MAX2980
AFE, form a complete HomePlug-compatible solution
with a substantially reduced system cost.

The MII/RMII/FIFO block is the interface layer of the
MAX2986 transceiver. This layer is designed to operate
with IEEE 802.3 standard MII, rMII, or any other devices
using the FIFO interface.
The interface is a data channel that transfers data in
packets, with flow controlled by the carrier sense
(MIICRS) signal. This signal controls the half-duplex
transmission between the external host and the MAC.
While a frame reception is in progress, (MIICRS and
