Broadcom B CM8 48 34 Q u ad 10 GBAS E- T Trans ce i ve r FOUR-PORT 10GBASE-T TRANSCEIVER Overview Highlights • The BCM84834 is a new member of the Broadcom® 40 nm 10GBASE-T PHY family. Features The Broadcom® BCM84834 is a complete quad 100BASE-TX, 1000BASE-T/10GBASE-T solution operating at 100m over CAT6a UTP cable. It is based on highly advanced digital signal processor architecture to enable robust operations over worst case UTP cables. The BCM84834 is a highly integrated solution combining enhanced analog front ends with digital adaptive equalizers, ADCs, phase-locked loops, line drivers, LDPC encoders and decoders, echo cancellers, crosstalk cancellers, and all required support circuitry. • Devices based on the 40 nm process offer an excellent long-term cost curve, enabling better cost reduction over time compared to legacy technologies. • EEE provides significant power reduction with AutogrEEEn® delivering EEE for legacy MACs • Optimized to enable switch, controller, and other general 10Gigabit Ethernet (GbE) connectivity applications. • Simplified systems design with only two supplies and with no external MDI components • Broadcom enhanced cable diag- Summary of Benefits • Simplifies system and board design – Reduces PCB space. – Lowers system bill of materials (BOM) • IEEE standard device interoperability: 100 Mbps, 1000 Mbps, and 10 Gbps. • Compatible with standard Ethernet MACs. • Cuts design constraints to meet EMI standards. • Cable diagnostics identifies cable plant condition to immediately trace cabling issues. • Operates with larger packets for increasedscale packet protocol support and efficiency. nostics estimates cable length and detects cable or termination anomalies XFI • 1588 Precision Time Protocol (PTP) provides precise and accurate synchronization of nodes in the network BCM84834 Service Provider OTN/PTN • Highly integrated four-port 10GBASE-T Ethernet transceiver. • Supports multiple speeds: 100BASE-TX and 1000BASE-T • XFI and SGMII MAC interface options • Compliant with IEEE 802.3™, IEEE 802.3an, IEEE 802.3ab, and IEEE 802.3u standards. • AutogrEEEn permits legacy MACs to receive the power savings of EEE in periods of reduced link utilization. • Synchronous Ethernet support • Low electromagnetic interference (EMI) emissions • 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 selected port. • IEEE 1149.1 (JTAG) boundary scan • Extensive selection of both line and network side loopbacks. • 676-pin FBGA 27 mm x 27 mm package XFI MAC Controller or Switch XFI MDI Transformer RJ-45 MDI Transformer RJ-45 MDI Transformer RJ-45 MDI Transformer RJ-45 BCM84834 Data Centers XFI Enterprise Supported Best Choice BCM84834 [Port 1] BCM84834 [Port 2] BCM84834 [Port 3] SYNC_IN0 IEEE 1588 / SynchE SYNC_IN1_OUT INTERR_MLC RD[1] + TD[1] + XFI Frame Frame Scramble Scramble LDPC LDPC Encode Encode 4D 4DDSQ DSQ 128 Map ™ XAUI ™ /SGMII /SGMII XFI SGMII MAC interface MAC Interface Deframe Deframe and and Descramble LDPC LDPC Decode Decode 4D 4DDSQ DSQ 128 128Soft Soft Decisions Decisions 4D Pre-H Decode Decode Matrix Matrix Xtalk Xtalk Canceller Canceller and and Equalizer Equalizer 4D DAC 4D Clock Recovery TRD[1][0:3] 4D 4DADC ADC BCM84834 [Port 4] MDC MDIO MDIO MDIO Management Interface Interface LED LED Controller Controller MII Registers 10 LEDs SI SCK CSb Clock Clock Generator Generator SPI SO + XTALN + XTALP Shared Functions BCM84834 Block Diagram for Each Port Each BCM84834 port contains one XFI interface to connect to the MAC side. This quad port enables customers to design high-density Top of the Rack (ToR) switches and server NIC controllers for data center applications. The 40 nm process offers the best performance, lowest cost, and lowest power consumption for 10-Gigabit copper applications and enables a highly integrated solution. The BCM84834 incorporates various advanced features. A link quality indicator LED provides instant notification of Ordering Information any problems with the wiring plant operating at the desired speed. These problems include physical wiring defects that the BCM84834 cannot automatically correct and channel conditions such as excessive cable length and return loss, crosstalk, echo, and noise.
