BCM5226_04 BOARDCOM [Broadcom Corporation.], BCM5226_04 Datasheet - Page 2

• Manufacturer Part Number: BCM5226_04
• Description: 10/100BASE-TX/FX HEX-? TRANSCEIVER
• Manufacturer: BOARDCOM [Broadcom Corporation.]

The Broadcom
independent Fast Ethernet transceivers. Each performs all the physical
layer interface functions for 100BASE-TX full-duplex or half-duplex
Ethernet on Category 5 twisted-pair cable and 10BASE-T full or half-
duplex Ethernet on Category 3, 4 or 5 cable. Each port may also be
configured for 100BASE-FX full or half-duplex transmission over fiber-
optic cabling when paired with an external fiber-optic line transceiver.
The BCM5226 chip performs 4B5B, MLT3, NRZI, and Manchester
encoding and decoding, clock and data recovery, stream cipher
scrambling/descrambling, digital adaptive equalization, line
transmission, carrier sense and link integrity monitoring, auto-
negotiation and RMII management functions.
The BCM5226 can be connected to a switch controller through the RMII
on one side and connects directly to the network media on the other side
through isolation transformers for UTP modes or fiber-optic transceiver
components for FX mode. The BCM5226 is compliant with the IEEE
802.3 standard.

The BCM5226 operates from a 2.5V power supply, which dramatically
lowers total power consumption compared to 3.3V and 5V designs. The
BCM5226 I/O operates at either 2.5V or 3.3V, for compatibility with
3.3V designs.
The BCM5226 is the first 10/100 Ethernet transceiver to incorporate the
Hewlett-Packard auto-Media Dependent Interface Crossover (Auto-
MDIX) feature. Originally specified in the IEEE 802.3ab Gigabit
Ethernet standard for Category 5 cable, the Auto-MDIX feature enables
the transceiver to automatically detect and correct a crossed cable. This
allows system installation and maintenance personnel to use crossover or
straight-through cables interchangeably, regardless of whether the cable
is attached to another switch, network interface card or repeater. This
capability eliminates incorrect connections due to cable mismatch,
making it easier and less expensive to install and operate 10/100 Ethernet
switches.
The BCM5226R supports RMII, and is available in a 160-pin plastic
quad flatpack package (PQFP); the BCM5226R supports SMII, and is
available in a 128-pin PQFP.
