Cost-Effective, Lowest Power 3.3V Fast Ethernet PHY
Broadcom’s Alti-PHY technology targets cost-sensitive
applications where basic Ethernet functionality is required. The
AC101-QF/TF 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 AC101-QF/TF,
making it particularly appealing for value brand and
small/medium business applications.
With a power dissipation of 280 mW, the AC101-QF/TF is the
industry’s lowest power Fast Ethernet PHY. In addition, the
AC101-QF/TF has several intelligent power-down states that
conserve power, yet allows products based on it to turn on
automatically when needed. The AC101-QF/TF 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 AC101-QF/TF 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 AC101-QF/TF 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 AC101-
QF/TF provides significant system design flexibility. These
numerous options allow the AC101-QF/TF to be designed into
many different applications, reducing the number of separate
transceivers needed to meet multiple design requirements.
For the system/MAC interface, seamless support is provided for
the Motorola QUICC products, such as the MPC68360 or the
MPC860T families, as well as a variety of other embedded
microprocessors. For the physical media connectivity, support is
provided for 10BASE-T, 100BASE-TX, and 100BASE-FX.
Applications
Applications for the AC101-QF/TF that take advantage of its
cost-optimized design and low power include:
• PCMCIA/CardBus cards
• LAN on Motherboard
• IP phones
• Cable modems
• Set-top boxes
• Print servers
• Wireless access points
• Embedded telecom
