®
FOUR-CHANNEL 3.125 GIGABIT ETHERNET CMOS TRANSCEIVER
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)
SUMMARY OF BENEFITS
• _{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.
