National Semiconductor Introduces the Industry’s Highest Performance LVDS 4x4 Crosspoint Switch

Power-Efficient Crosspoint Delivers Unparalleled 10 ps Jitter Performance for Telecom, Video Routing, and ATE Applications at Data Rates Up to 3.125 Gbps

Sep 4, 2007

September 4, 2007 – A new low-voltage differential signaling (LVDS) 4 x 4 crosspoint switch from National Semiconductor Corporation (NYSE:NSM) delivers the industry’s best jitter performance (10 ps typical) at data transmission rates up to 3.125 Gbps. The DS25CP104 is well-suited for clock and data switching/routing in telecom, professional video, storage and automated test equipment (ATE) applications. The low-power LVDS device’s superior jitter and signal conditioning performance enables OEMs to use less costly cable, connectors and components. National will demonstrate the DS25CP104 at the International Broadcasting Convention (IBC) in Amsterdam from September 7-11 at Hall 11, Booth # 441.

The DS25CP104 offers a feature set to enhance signal integrity in demanding applications such as XAUI (telecom) and SMPTE 424M (pro video). For example, the product consumes only 122 mW per channel while boosting and equalizing field-programmable gate array (FPGA) or applications-specific integrated circuit (ASIC) signals over cables and FR-4 backplanes. The device inputs have a wide common-mode voltage range that allows it to accept low-voltage positive-emitter-coupled logic (LVPECL), current-mode logic (CML) and LVDS signal levels without using coupling capacitors. The system designer has maximum flexibility configuring the DS25CP104 with external pin control or a serial System Management (SM) Bus. The crosspoint also features 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.

National also is introducing the DS10CP154, a lower-speed, lower-power 4 x 4 crosspoint switch targeted at applications up to 1.5 Gbps, that includes many of the same features as the DS25CP104.
