Featuring lowest power consumption, Broadcom introduces CMOS 40G serial Mux/Demux chipset

By Telecom Lead Team: Broadcom has introduced two new
chipsets in its expanding line of 40 gigabit products.


The company claims that the two serial
multiplex/demultiplex (mux/demux) chipsets are the world’s first 40G CMOS-based
solutions that enable tri-rate CFP (C-form pluggable) modules and VSR/DPSK
applications (very short reach/differential phase shift keying).


These new products are the latest innovations to join
Broadcom’s expanding line of high-speed 10G/40G/100G products. These chipsets
also represent an important breakthrough for the industry by enabling OEMs to
take advantage of 40nm CMOS process technology with the inherent advantages of
lower power consumption and increased reliability,” said Lorenzo Longo, vice
president & general manager, High Speed Interconnect Products, Broadcom.


Both of the mux/demux chipsets gain from 40nm process
nodes and are engineered to achieve best-in-class performance. They also
deliver the industry’s lowest power consumption – only two watts combined and
60 percent lower than the nearest competitor.


Further propelling 40G growth is the industry’s
increasing use of wave division multiplexing (WDM) and Sonet/SDH (synchronous
digital hierarchy) solutions.(2)  Broadcom’s newest 40G chipsets are
engineered to meet the demand for higher bandwidth and designed to handle a
wider range of applications while reducing power consumption up to 60 percent
less than the nearest competitor.


The company claims that both chipsets offer high-speed
data rate support ranging from 39.8 to 44.6 Gbps.  They are also available
in standard 14mm x 14mm BGA (ball grid array) packages. Competing solutions
require the use of ceramic packages and GPPO interfaces for high speed 40G
I/Os.  The use of standard BGA packaging results in a substantial decrease
to the total system cost.


AT&T has been deploying 40G extensively across our
network since 2005.  Broadcom’s 40G CMOS chipset enables the new CFP
tri-rate modules and applications that are key to continuous cost reduction and
network growth for AT&T and others,” said Jim King, executive director of
Optical Technology Planning and Development,
