BCM84848 Quad 10GBASE-T Transceiver

FOUR-PORT 10GBASE-T TRANSCEIVER

Highlights
• The BCM84848 delivers a
second-generation 40 nm 10GBASE-T PHY in a small 23 x 23 mm BGA package.
• Standard 1RU switching plat-
forms can implement a singlerow PHY design with this 23 x 23 mm package
• Energy Efficient Ethernet EEE is
now delivered on all network speeds 10GBASE-T, 1000BASET, and 100BASE-TX. EEE provides significant power reduction, and enables EEE with legacy MACs.
• Quad 10GBASE-T PHYs are ideal
for 48-port, top of rack ToR switches, and 4x 10GbE adapters.
• Simplified system design with
only two power supplies and no external MDI components.
• 1588 Precision Time Protocol

PTP provides precise and accurate synchronization of nodes in the network.
• 802.1ae MACsec Security.

Overview

The 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.

Summary of Benefits
• 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.

to support virtually all switch/PHY connections for ToR switches. Support for EEE is provided both through LPI commands over the XFI interface and via Broadcom's AutogrEEEn feature. EEE is supported for all three speeds 10GBASET, 1000BASE-T, and 100BASE-TX. Support for 1588v2 in the BCM84848 is part of Broadcom's broad offering of PTP devices. The IEEE 802.1ae MACsec
implementation is part of Broadcom's broad offering of security devices.

The BCM984848_16PORT is available and provides a reference design platform suitable for evaluation of the device. A design guide is provided as part of the device support information. Contact your Broadcom sales representative for information.
