National Semiconductor Introduces Lowest-Power, Easy-to-Use Cable Extender Chipset

via PRNewswire

SANTA CLARA, Calif., Feb. 26 /PRNewswire-FirstCall/ -- National Semiconductor Corporation (NYSE: NSM), a leading supplier of high-performance analog signal-path products, today introduced the industry's lowest power cable extender chipset that boosts the reach of 0.15 Gbps to 1.5 Gbps LVDS, LVPECL, and CML signals up to 400 meters over copper cable with only 360 mWpower consumption. National built this easy-to-use chipset 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 innovative DS15BA101 and DS15EA101 cable extender chips etextends serial data streams from serializer/deserializer (SerDes) and field programmable gate arrays (FPGAs) over CAT5 and coaxial cable at up to half the cost of fiber optic solutions. Previously, LVDS/LVPECL/CML signals were limited to less than 20 meters of cable. Engineers have been seeking an easyway to bridge longer distances over low-cost copper cables, and National's cable extender chipset and complete reference design now gives them the flexibility to easily extend that reach for remote cameras and displays, remote radio head (RRH) base stations, high-speed test equipment, industrial machine vision systems and many other industrial-grade applications.

Complete Reference Design

The Drive Cable 002EVK reference design features everything engineers need -- including evaluation system, schematic and printed circuit board (PCB) layout Gerber files -- to quickly and easily evaluate and integrate the cable extender chipset into their design. It plugs directly into a designer's existing system and supports CAT5/5e/6/7 100-Ohm twisted pair cables up to 100 meters and 50-Ohm coaxial cables up to 400 meters.

Cable Extender Chipset Technical Features

The DS15BA101 differential buffer is an adjustable cable driver offered in a space-saving 3 mm by 3 mm 8-pin LLP(R) package. The device is powered from a single 3.3V supply and consumes 150 mW (typical) at 1.5 Gbps. The DS15BA101 operates over the full .40 degrees C to 85 degrees C industrial temperature range. In addition to being used with the DS15EA101 adaptive equalizer as a cable extension chipset, the DS15BA101 cable driver also can be used stand alone for level translation between LVDS/CML/LVPECL and CML or LVPECL.

With no packet formatting, training or comma characters required, the chipset automatically adapts to different cable types, cable lengths, datarates and data formats without external programming, providing an easy-to-use alternative to fiber and Ethernet solutions.
