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
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 EyeOpener^TM 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
