DM9801E Product Brief 1M Home Phoneline Network Physical Layer Single Chip Transceiver June 2008 Rev.1.0 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. 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.
