Cost-Effective, Lowest Power 3.3V Fast Ethernet Broadcom's Alti-PHY technology targets cost-sensitive applications where basic Ethernet functionality required. AC101-QF/TF provides required features fully compliant IEEE 802.3u 10/100BASE-TX/FX transceiver. full custom circuit design optimizes cost AC101-QF/TF, making particularly appealing value brand small/medium business applications. With power dissipation AC101-QF/TF industry's lowest power Fast Ethernet PHY. addition, AC101-QF/TF several intelligent power-down states that conserve power, allows products based turn automatically when needed. AC101-QF/TF includes unique intelligent power-management feature that powers down device energy detected cable. This feature especially useful portable power-sensitive applications, such laptop card adapters. AC101-QF/TF allows PCMCIA CardBus adapters remain plugged draw virtually energy even client longer connected network. Because most laptop users remove their cards when working remotely, this feature results noticeably extended battery life laptop computer users. lowest power consumption, AC101-QF/TF power-down state (<3.3 mW).
With three different physical media interfaces, four different system interfaces, multiple packages available, AC101QF/TF provides significant system design flexibility. These numerous options allow AC101-QF/TF designed into many different applications, reducing number separate transceivers needed meet multiple design requirements. system/MAC interface, seamless support provided Motorola QUICC products, such MPC68360 MPC860T families, well variety other embedded microprocessors. physical media connectivity, support provided 10BASE-T, 100BASE-TX, 100BASE-FX. Applications Applications AC101-QF/TF that take advantage cost-optimized design power include: PCMCIA/CardBus cards Motherboard phones Cable modems Set-top boxes Print servers Wireless access points Embedded telecom
