AC101TF

The AC101TF has the following features including (1)Cost optimized, full custom circuit design;(2)10BASE-T/100BASE-TX/FX IEEE 802.3u Fast Ethernet transceiver;(3)Power consumption: <280 mW;(4)Unique energy detection circuit to enable intelligent power management;(5)Selectable TX drivers for 1:1 or 1.25:1 transformers to enable additional power reduction.

Broadcom's Alti-PHY technology targets cost-sensitive applications where basic Ethernet functionality is required. The AC101TF provides all of the required features of a fully compliant IEEE 802.3u 10/100BASE-TX/FX transceiver. A full custom circuit design optimizes the cost of the AC101TF, making it particularly appealing for value brand and small/medium business applications.With a power dissipation of 280 mW, the AC101TF is the industry's lowest power Fast Ethernet PHY. In addition, the AC101TF has several intelligent power-down states that conserve power, yet allows products based on it to turn on automatically when needed. The AC101TF includes a unique intelligent power-management feature that powers down the device if energy is not detected on the cable. This feature is especially useful for portable and power-sensitive applications,such as laptop LAN card adapters. The AC101TF allows PCMCIA or CardBus adapters to remain plugged in and draw virtually no energy even if the client is no longer connected to the network.

Because most laptop users do not remove their LAN PC cards when working remotely, this feature results in a noticeably extended battery life for laptop computer users. For lowest power consumption, the AC101TF can be put in a power-down state (<3.3 mW).With three different physical media interfaces, four different system interfaces, and multiple packages available, the AC101TF provides significant system design flexibility. These numerous options allow the AC101TF to be designed into many different applications, reducing the number of separate transceivers needed to meet multiple design requirements.The information presented in this document does not form part of any quotation or contract, is believed to be accurate and reliable and may be changed without notice.
