full feature set in addition to robust performance, the digi- products come with features that ease design and manufacturing. multi-port phys have both rmii and smii interfaces, while the single- port solutions have rmii and mii. the latest digi- s operate at 1.8v. in addition, the digi- s provide full led support and feature programmability and serial mode support in multi-port solutions. all of these features create options that make it easier for engineering to design a system solution. when the design is complete, ieee 1149.1 (jtag) scan chain support lowers the cost of putting the design through production. digi- ? technology the broadcom brand employs dsp phy design and full- custom circuit design techniques to create a highly integrated and robust physical layer solution. dsp techniques allow broadcom phys to achieve high interoperability and to exhibit robust performance across voltage, temperature, and process variations. broadcom's digi- core is the world's most proven 10/100 phy architecture, deployed worldwide in over 250 million fast ethernet ports. since 1998, the same digi- architecture has been successfully implemented and proven in 0.5 micron, 0.35 micron, 0.22 micron, and 0.18 micron single- poly cmos processes. the digital nature of broadcom's digi- architecture is far more portable than competitive analog solutions, which must be redesigned as they migrate from one manufacturing process to another. it also allows for substantially higher test coverage, resulting in inherent advantages in manufacturing and outgoing quality. broadcom's family of digi- transceivers offers the world's highest level of outgoing quality, well below 10 parts per million (ppm). network tolerance broadcom s latest digi- offerings include features that simplify the installation, debugging, and maintenance of local area networks. one such feature is the hp auto-mdix capability, which automatically and transparently detects and corrects crossed cables. with hp auto-mdix, the installer does not need to know what ethernet equipment is on the other end of the network cable: any cable can be used to connect to a switch, repeater, nic, or router. in addition, broadcom s latest digi- s are designed and tested to withstand over 9kv of cable- sourced electrostatic discharge (cesd), a recently discovered phenomenon that occurs when an electrically charged network cable is plugged into networking equipment. the high tolerance for cesd protects the system from destruction caused by this electrical discharge during installation and cable insertion. standalone phys: single and multi-port integrated standard products (e.g. 5318) integrated asics over 250 million ports alti- ? technology broadcom s value brand targets cost-sensitive applications where basic ethernet functionality is required. the alti- technology is fully compliant with ieee 802.3/802.3u and features the industry s lowest power consumption at 3.3v. the optimized die size and process geometry for the alti- family of products enable an aggressive price structure. with fully compliant ethernet functionality and an extremely low power consumption, the alti- family presents a compelling set of solutions for the basic ethernet market. broadcom s digi- core is ported easily from one product to the next, from one process to the next. portability is the key to broadcom s rapid product introduction in standalone phys and integrated switches. broadcom is driving rapid growth in custom asics using customer owned technology integrated with the digi- core. 10/100 phy transceiver fast ethernet based networks continue to be the workhorse for business communications. broadcom has developed a portfolio of 10/100base-tx/fx phy transceivers that provide innovative solutions for this market. these offerings include a full-featured broadcom brand and a cost-effective value brand.
