BCM8011 ® FOUR-CHANNEL 3.125 GIGABIT ETHERNET CMOS TRANSCEIVER SUMMARY OF BENEFITS 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 0.18µ standard CMOS process technology (1.8V and 2.5V supplies) 2.5W nominal power 324-pin FBGA package (19 mm x 19 mm) • 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.
