CMOS 100G Transmitter PHY combines speed and low power draw.

Press Release Summary:

Enabling high-capacity, 100G optical modules and line-card designs, BCM84128 is implemented in 40 nm CMOS process technology, consumes less than 2 W, and achieves aggregate data rate of 128 Gbps with four 32.1G lanes. Solution is designed for long-haul, regional, and metropolitan data transport and provides respective full- and half-rate clock outputs at 32 and 16 GHz. Features such as clock and data skew control adjust lane-to-lane skew and date-to-clock skew on line-side interface.

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

Enables Higher Density 100G Long Haul, Regional and Metro Optical Transport

ANAHEIM, Calif. -- OFC/NFOEC Technical Conference 2013 --

News Highlights:

--  Consumes 60 percent lower power than competitive devices (less than two watts)

--  Achieves aggregate data rate of 128Gbps with four 32.1G lanes

--  Higher reliability and testability enabled through proven 40 nm CMOS process technology

Broadcom Corporation (NASDAQ: BRCM), a global innovation leader in semiconductor solutions for wired and wireless communications, today announced the world's fastest CMOS transmitter PHY for long-haul, regional and metropolitan data transport. Broadcom's BCM84128 100G transmitter achieves an aggregate data rate of 128 Gbps at the industry's lowest power of two watts, enabling high-capacity, 100G optical modules and line-card designs.

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.

Industry's Broadest Portfolio for Optical Transport

A leading provider of optical transport solutions that enable high-capacity, carrier-grade routers and switches, Broadcom is paving the way to 100G long-haul optical networks with an end-to-end portfolio of switching fabrics and physical layer technology.


The BCM84128 transmitter PHY is now sampling with volume production slated for Q2 2013. See Broadcom's complete portfolio of optical networking solutions at OFC/NFOEC booth #1052.
