Broadcom BCM5221
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 10BASET/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.| Part No. | BCM5221 |

GENERAL DESCRIPTION
The BCM5221 operates at 3.3V or 2.5V. 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 mixedsignal implementations, such as analog offset and onchip noise, are eliminated by employing field proven digital adaptive equalization and digital clock recovery techniques.FEATURES
