Broadcom Introduces World's Fastest and Lowest Power 100G Transmitter PHY

Increased demand for broadband applications such as on-demand services and streaming video is exerting pressure on long-haul and metro networks, driving the need for higher data transmission rates. According to analyst firm Dell'Oro, demand for 100 Gbps optical transport continues to grow as networks upgrade to terabit-capacity equipment in long haul and metro applications. Dell'Oro forecasts 100 Gbps shipments to grow ~140 percent in 2013.

The BCM84128 high performance transmitter PHY reflects the industry-leading innovation we are known for, allowing OEMs to leverage 100G PHYs developed in standard CMOS process technology with its inherent advantages of lower power and reliability, said Lorenzo Longo, Broadcom Vice President and General Manager, Physical Layer Products (PLP). Today's introduction provides Broadcom with the opportunity to participate in a new market segment and pave the way for 100G optical transport.

The BCM84128 transmitter implemented in 40 nanometer (nm) CMOS process technology provides a full-rate clock output at 32 GHz and a half-rate clock output at 16 GHz. Advanced features such as clock and data skew control adjust the lane-to-lane skew and the date-to-clock skew on the line-side interface.
