New Crosspoints from National's PowerWise Energy-Efficient Product Family
Consume Less Than 125 mW per Channel, With Jitter Performance as Low as 6
ps at Data Rates up to 3.125 Gbps
SANTA CLARA, Calif., Nov. 19 /PRNewswire-FirstCall/ -- National
Semiconductor Corporation (NYSE: NSM) today added two low-power,
low-voltage differential signaling (LVDS) 2x2 crosspoint switches to its
PowerWise(R) energy-efficient product family. The DS25CP102 delivers the
industry's best jitter performance (6 ps typical) at data transmission
rates up to 3.125 Gbps, while consuming only 125 mW of power per channel.
The device features selectable transmit pre-emphasis and receive
equalization to extend signal transmission reach in cables and FR-4
backplanes. The lower-speed (1.5 Gbps) DS10CP152 addresses short-haul
applications that do not require signal conditioning. It delivers excellent
jitter performance (9 ps typical), with very low power consumption of 57 mW
per channel.
The DS25CP102 and DS10CP152 work as splitters or multiplexers for
high-speed signal routing and switching in OC-48 telecom as well as
standard-definition (SD), high-definition (HD) and 3-Gbps serial digital
interface (SDI) professional video applications. They are also used in
video and imaging transport applications to select between two data streams
or as a splitter to drive two monitors. Their superior jitter and signal
conditioning performance allow OEMs to use less costly cable, connectors
and components. National built these 2x2 crosspoint switches with its
proprietary silicon-germanium (SiGe) BiCMOS-8 process technology, which
provides the highest performance-to-power ratios for high-speed interface
devices.
National's 2x2 crosspoints offer pin-selectable signal-conditioning
features to reduce data-dependent jitter and eliminate the need for
repeaters to extend signal transmission reach. Their inputs have a wide
common-mode voltage range that allow the crosspoints to accept low-voltage
positive-emitter-coupled logic (LVPECL), current-mode logic (CML) and LVDS
signal levels without using coupling capacitors. The DS25CP102 and
DS10CP152 accept signals directly from the leading 90 nm and 65 nm
field-programmable gate arrays (FPGAs) and application-specific integrated
circuits (ASICs). They feature 8 kV electrostatic discharge (ESD)
protection and 100-Ohm termination on the LVDS input and output pins to
minimize insertion losses, component count and board space.
These devices are the latest additions to National's growing family of
crosspoint switches, which include the recently announced DS25CP104 and
DS10CP154 LVDS 4x4 crosspoints.
