The BCM5221 is a single channel, low-power,10/100BASE-TX/FX transceiver targeting a number ofapplications requiring intelligent power management androbust network tolerance. The BCM5221 operates at3.3V 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 functionsfor 10BASE-T Ethernet on CAT 3, 4, and 5 unshieldedtwisted pair (UTP) cable and 100BASE-TX Fast Etherneton CAT 5 UTP cable. In addition, layout compatibility withthe previous generation BCM5201 shortens the designcycle for the BCM5221. 100BASE-FX is supportedthrough the use of external fiber-optic transmit andreceive devices.

The Broadcom® BCM84848 is a complete quad 100BASE-TX, 1000BASE-T and 10GBASE-T solution operating at 100m over CAT6a UTP cable. Its 23 x 23 mm BGA package permits 48-port 1RU switches to be implemented with the PHYs in a single row, with room remaining for 6 QSFP uplinks. The BCM84848 offers lower power than our firstgeneration 40 nm 10GBASE-T PHYs while adding Energy Efficient Ethernet (EEE) for 1000BASE-T and 100BASE-TX, in addition to 10GBASE-T. Optional Adaptive Voltage Scaling (AVS) delivers a low power solution while enabling a low cost implementation. The BCM84848 is based on a highly advanced digital signal processor architecture to enable robust operations over worst case UTP cables.
Small 23 x 23 mm package enables single-row PHY design for 48-port switches while offering forward compatible footprint • Robust operation over 100m Cat6a cables with industry-standard 4-pair magnetics. • Auto-negotiation lowers system administration cost. • EEE on GbE delivers lower power for legacy interconnections. • IEEE standard device interoperability: 100 Mbps, 1000 Mbps, and 10 Gbps. • Cuts design constraints to meet EMI standards.• Cable diagnostics identifies cable plant condition to immediately trace cabling issues. • 1588v2 with one-step timestamp insertion provides high accuracy timing. • 802.1ae MACsec provides link layer security
• Highly integrated four-port 10GBASE-T Ethernet transceiver. • Supports multiple speeds: 10GBASE-T as well as 100BASE-TX and 1000BASE-T. • XFI and SGMII MAC interface options. • Compliant with IEEE 802.3, IEEE 802.3an, IEEE 802.3ab, IEEE 802.3u, and IEEE 802.3az standards. • AutogrEEEn technology permits legacy MACs to receive the power savings of EEE in periods of reduced link utilization. • Reduced number of power supplies with standard voltages: 1.0V and 2.5V. • AVS for the creation of a local DVdd supply from a 3.3V global supply. • Synchronous Ethernet (SyncE) support. • Cable plant diagnostics. • IEEE standard 1588-2008 (version 2) support. • Detection and correction of pair swaps (MDI crossover), pair skew, and pair polarity. • Support for jumbo packets up to 18 KB. • Super-Isolate mode to completely disable a selected port. • IEEE 1149.1 (JTAG) boundary scan. • Extensive selection of both line and network side loopbacks.
