BCM8073 Brief DUAL-CHANNEL SERIAL 10GBASE-KR TO XAUI TRANSCEIVER FEATURES SUMMARY OF BENEFITS Two 10G-XAUI interfaces in one compact package Targeted to meet the IEEE 802.3ap standard High-performance DFE/FFE receive equalizer with full High-performance equalization supports new and legacy adaptation on chip backplane channels. Multitap transmit preemphasis with automated start-up XAUI and 10G differential pairs can be reversed to facilitate routine layout. Auto-negotiates to 1.25G/10G Enhanced diagnostics provide users with signal quality monitors. Complete 1G and 10G PCS layers Single 156.25-MHz or 25-MHz REFCLK reduces overall Low-power equalization mode for shorter reach stackable linecard BOM cost. systems Low-latency design for high-performance computing. Programmable amplitude control on 10G serial transmitter Selectable FEC encoder/decoder for added performance Broadcom Signal Integrity Tool - LINKEYE(TM) assists customers with high-speed system designs. Input sensitivity 20 mV peak-to-peak differential Multiple interface support APPLICATIONS - PMD interface: Serial 10.3125-Gbps CML - 4-lane XAUI (3.125 Gbps) Backplane links Low-power 65-nm CMOS design with 1.2W/10G KR port Copper-cable stackable links Core supply1.0V, I/O3.3V Onboard and board-to--board links Loss-of-signal detection On-chip diagnostics include 10G eye monitor, SNR, and BER monitors Integrated packet generator and checker 19 mm x 19 mm, 1-mm pitch, 324-pin BGA, RoHS compliant package BCM8073 Functional Block Diagram XAUI Media 10GBASE-KR 10.3125 Access RS XGXS MAC 1000BASE-KX Gbps Controller Interface XAUI Media BCM8073 RS XGXS Access MAC Controller 10GBASE-KR 10.3125 Interface 1000BASE-KX Gbps 25M or RE FCLK 156.25M MDC MDIO (x2) Management Interface Backplane Connector (x2)OVERVIEW x2 BCM8073 Block Diagram The BCM8073 is a dual-channel 10-GbE serial transceiver targeting the The BCM8073 dual Ethernet 10GBASE-KR PHY is a fully integrated new IEEE 10GBASE-KR standard for running 10G serial data over dual SerDes (10.3125 Gbps) interface device performing the extension backplane systems. The device incorporates sophisticated receive functions for a 10-GbE reconciliation sublayer (RS) interface. The equalizers, which extend the life of legacy systems currently running at XGXS, PCS, and PMA include 8B/10B coding, 64B/66B coding, 1G or XAUI data rates by providing a 4x or 10x bandwidth improvement SerDes, a clock multiplication unit (CMU), and clock and data recovery on each channel. (CDR). On-chip clock synthesis is performed by the high-frequency, low-jitter Polarity of the XAUI and 10G differential pairs can be reversed to phase-locked loops (PLL) for the PMD and XAUI output retimers. facilitate layout. The ordering of the XAUI lanes can also be changed. Individual PMD and XAUI clock recovery is performed on the device by The BCM8073 is available in a 19 mm 19 mm, 1-mm pitch, 324-pin synchronizing directly with the respective incoming data streams. An BGA, RoHS-compliant package. external 25-MHz or 156.25-MHz oscillator is required for the reference clock input.
