Home Networking Physical Layer Device with Integrated Analog Front End Circuitry
This document describes the CN7221 Home Networking Physical Layer (PHY) with Integrated Analog Front End (AFE). It includes device pinouts, signal descriptions, and timing diagrams. The CN7221 allows home networks to operate over common telephone wires at 1 Mbps. The CN7221 simplifies system designs and improves their reliability by eliminating the need for a separate AFE comprised of discrete components. The CN7221 supports the emerging home phoneline networking standard proposed by the Home Phoneline Networking Alliance (HomePNA). Conexant has announced plans to release a family of multifunction home phoneline networking chipsets. The first products to be announced in this family include the RS7111A 1/10/100 PCI/CardBus Multifunction Controller, the RS7220 Home Networking PHY, the RS7112 Multifunction Controller with Integrated PHY, and the CN7221 Home Networking PHY with Integrated AFE (see Ordering Information, page 2). DataSheet4U.com The HomePNA phoneline network utilizes existing telephone wiring to connect computers and devices without interrupting phone service. Industry-standard home networking products will enable a variety of home computing opportunities including shared Internet access using a single phone line printer/peripheral sharing file and application sharing networked gaming
