| BCM8011 (R) FOUR-CHANNEL 3.125 GIGABIT ETHERNET CMOS TRANSCEIVER FEATURES * Support for four channels of 3.125 GigaBaud per second (GBd) * * * * * * * * * * * * resulting in an effective aggregate data rate of 10 Gigabits per second (Gbps) Support for the 10 Gigabit attachment unit (XAUI) and 10 Gigabit media independent interface (XGMII) proposed by the IEEE 802.3ae standards Less than 3 ps Root Mean Square (RMS) transmit jitter using Broadcom's LC-VCO technology 32 bytes of de-skewing capability for the channels 32-bit parallel interface compatible to SSTL_2/HSTL (1.5) Class I EIA/JEDEC specifications On-chip phase-locked loop (PLL), providing clock synthesis from 156.25 MHz clock references Optional 8B/10B encoder and 10B/8B decoder in each channel Parallel or serial loopback modes Built-In Self-Test (BIST) capability Termination resistors on-chip Implemented in a 0.18 standard CMOS process technology (1.8V and 2.5V supplies) 2.5W nominal power 324-pin FBGA package (19 mm x 19 mm) SUMMARY OF BENEFITS * Enables data transfer rate of 10 Gbps over metropolitan * * * * network when used with wavelength division multiplexing (WDM) or XAUI interface to a serial 10-Gbps laser module. Ultra-low transmitter jitter on each channel results in a longer cable reach (in excess of 40 km). EyeOpenerTM adaptive equalizer extends the speed and reach of copper traces over FR4 backplane. Adaptive equalization and ultra-low receiver jitter enhance the receive eye pattern, which results in a superb bit-error rate (BER). Easy-to-use programming of the global configuration registers facilitates the design of the system. It provides enable/disable functions such as PLL lock, channel synchronization, VCO bypass, serial and loopback modes for self-diagnosis, and selecting source-centered and source-synchronous clocking. In-system at-speed link and on-board Built-In-Self-Test (BIST) is available using programmable pseudo-random bit sequence (PRBS) and programmable pattern comparators. * BCM8002 BCM8002 1G Modules BCM8002 BCM8002 BCM5632 Switch Processor TBI XGMII BCM8011 XAUI-XGMII Transceiver XAUI 10 GbE Backplane BCM8002 BCM8002 P Memory Application Diagram OVERVIEW TMS TCK TDI TDO TRSTb MDIO MDC IEEE 1149.1 JTAG Configuration Control Clock Multiplier Unit PLL TX[31:0] TX[7:0] TX_CLK REFCLK Input FIFO 8B/10B Encoder Serializer TD(3:0)+ TD(3:0) Rloop RX[31:0] RXC[7:0] RX_CLK RX_CLKC RST Synchronize De-Skew 10B/8B Decoder Optional Adaptive Equalization Clock Recovery De-Serializer RD(3:0)+ RD(3:0) The BCM8011 chip provides an aggregate bandwidth of 10-Gbps fullduplex, extending Ethernet capabilities into the Wide Area Network (WAN). The BCM8011 integrates four channels of the Broadcom FusionCore TM - a high-performance mixed-signal transceiver core, capable of transmitting and receiving data at 3.125 Gigabits per second (Gbps). The chip also supports Broadcom's EyeOpenerTM adaptive equalizer, which improves overall cable reach and compensates for the electrical imperfections associated with the copper traces and connectors. Fully integrated PLL and Clock and Data Recovery enable individual channels to lock to the incoming data. The unique design of the LC-VCO and CDR blocks have resulted in a less than 3 ps Root Mean Square (RMS) transmit jitter implemented in CMOS. The transmitter section accepts 32-bit-wide (XGMII) parallel SSTL_2/ HSTL-compatible data, clock and control signals and serializes the 32bit data into a 4-differential pair of CML high-speed data (XAUI). The receiver section enables individual channels to lock to the incoming data. The recovered data is presented at the SSTL_2/HSTL-compatible parallel outputs. The optional 8B/10B encoding and 10B/8B decoding of the PCS layer are integrated in the transceiver. Channel alignment and synchronization capabilities are addressed through configuration registers. Broadcom also offers a complete evaluation kit, including board and related software running on the Microsoft(R) Windows(R) 98 or Windows(R) NT 4.0.
