General Description
The DM9801 is a physical-layer, single-chip, low-power
transceiver for 1M Home Phoneline Network applications.
On the media side, it provides an interface to a Home
Phoneline wiring system. The reconciliation layer interfaces
to the DM9801 either through an IEEE802.3u subset Media
Independent Interface (MII) or a pseudo-standard General
Purpose Serial Interface (GPSI). A management interface is
provided by MDIO/MDC when operating in MII mode, or a
Serial Peripheral Interface bus when operating in GPSI
mode.
Block Diagram
The DM9801 uses a low-power and high-performance
CMOS process. It contains the entire physical layer
functions of 1M as defined by Home Phoneline Network
Alliance, Rev. 1.1, including the Physical Coding
Sublayer, (RLL25) Encoder/Decoder (ENC/DEC), 4-wire
HN Driver circuit and receiver analog front end (AFE).
Patent-Pending Circuitry Includes:
An enhanced 4-wire Home Network transceiver circuit.
