BCM8011
FOUR-CHANNEL 3.125 GIGABIT ETHERNET CMOS TRANSCEIVER
Application Diagram
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)

Backplane
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).
EyeOpener
TM
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.
