Application Diagram
•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.
SUMMARY OF BENEFITS
FOUR-CHANNEL 3.125 GIGABIT ETHERNET CMOS TRANSCEIVER
PRODUCT
Brief
BCM8011
•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)
The BCM8011 chip provides an aggregate bandwidth of
10-Gbps full-duplex, extending Ethernet capabilities into the
Wide Area Network (WAN). The BCM8011 integrates four
channels of the Broadcom FusionCoreTM — 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 32-bit 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®Windows®98 or
Windows®NT 4.0.
Applications:
• 10 Gigabit Ethernet LAN, MAN, WAN switches and routers
• Next-generation network interface cards
• Fiber headends
• Advanced Test Equipment (ATE)
• High-speed serial copper connections
