BCM8011
FOUR-CHANNEL 3.125 GIGABIT ETHERNET CMOS TRANSCEIVER
FEATURES SUMMARY OF BENEFITS
Support for four channels of 3.125 GigaBaud per second (GBd)
Enables data transfer rate of 10 Gbps over metropolitan
resulting in an effective aggregate data rate of 10 Gigabits per
network when used with wavelength division multiplexing
second (Gbps)
(WDM) or XAUI interface to a serial 10-Gbps laser module.
Support for the 10 Gigabit attachment unit (XAUI) and 10
Ultra-low transmitter jitter on each channel results in a longer
Gigabit media independent interface (XGMII) proposed by the
cable reach (in excess of 40 km).
IEEE 802.3ae standards

EyeOpener adaptive equalizer extends the speed and reach
Less than 3 ps Root Mean Square (RMS) transmit jitter using
of copper traces over FR4 backplane.
Broadcoms LC-VCO technology
Adaptive equalization and ultra-low receiver jitter enhance
32 bytes of de-skewing capability for the channels
the receive eye pattern, which results in a superb bit-error rate
32-bit parallel interface compatible to SSTL_2/HSTL (1.5)
(BER).
Class I EIA/JEDEC specifications
On-chip phase-locked loop (PLL), providing clock synthesis
Easy-to-use programming of the global configuration registers
from 156.25 MHz clock references
facilitates the design of the system. It provides enable/disable
functions such as PLL lock, channel synchronization, VCO
Optional 8B/10B encoder and 10B/8B decoder in each channel
bypass, serial and loopback modes for self-diagnosis, and
Parallel or serial loopback modes
selecting source-centered and source-synchronous clocking.
Built-In Self-Test (BIST) capability
In-system at-speed link and on-board Built-In-Self-Test
Termination resistors on-chip
(BIST) is available using programmable pseudo-random bit
Implemented in a 0.18 standard CMOS process technology
sequence (PRBS) and programmable pattern comparators.
