BCM5221
10/100BASE-TX/FX Mini-Φ™ Transceiver
GENERAL DESCRIPTION
The BCM5221 is a single channel, low-power,
10/100BASE-TX/FX transceiver targeting a number of
applications requiring intelligent power management and
robust network tolerance. The BCM5221 operates at
3.3V or 2.5V. The devices contain a full-duplex 10BASE-
T/100BASE-TX/100BASE-FX Fast Ethernet transceiver,
which performs all of the physical layer interface functions
for 10BASE-T Ethernet on CAT 3, 4, and 5 unshielded
twisted pair (UTP) cable and 100BASE-TX Fast Ethernet
on CAT 5 UTP cable. In addition, layout compatibility with
the previous generation BCM5201 shortens the design
cycle for the BCM5221. 100BASE-FX is supported
through the use of external fiber-optic transmit and
receive devices.
The BCM5221 is a highly integrated solution combining a
digital adaptive equalizer, ADC, phase lock loop, line
driver, encoder, decoder and all the required support
circuitry into a single monolithic CMOS chip. It complies
fully with the IEEE 802.3u specification, including the
Media Independent Interface (MII) and Auto-Negotiation
subsections.
The effective use of digital technology in the BCM5221
design results in robust performance over a broad range
of operating scenarios. Problems inherent to mixed-
signal implementations, such as analog offset and on-
chip noise, are eliminated by employing field proven
digital adaptive equalization and digital clock recovery
techniques.
