Rockwell Scientific Expands Its High Performance Dual Track and Hold Family for Ultra-wideband Data Acquisition; Device Dramatically Increases ADC Bandwidth

Business Wire, Nov 16, 2004

THOUSAND OAKS, Calif. -- Rockwell Scientific Company LLC (RSC), a premier developer of high speed mixed signal circuits for commercial and defense applications, announced that the company is expanding its dual track and hold family of products. The first of these, the RTH011, is a 10 GHz bandwidth 1 GS/s dual track and hold (T/H) circuit with extended hold time for ultra-wideband data acquisition.

The bandwidth of the RTH011 -- over 10GHz for small signals, 9GHz for 0.5 Vpp and 7GHz for 1 Vpp inputs -- combined with an extended hold time, enables ultra-wideband signal capture with greater flexibility than currently available. The interface to subsequent circuitry, such as ADCs, became easier and more affordable by allowing the use of a low-frequency sampling clock. With well under 1 mV noise and 100 fs aperture jitter, the RTH011 achieves a 67 dB spurious free dynamic range (SFDR) and a -64 dB total harmonic distortion (THD) for a 1060 MHz, 1 Vpp input signal.

Thanks to its ultra-wide input bandwidth, RSC's track and holds have enabled many applications including direct conversion of multi-GHz carrier signals and sampling of extremely high-speed signal edges on the 20ps rise time range. "We have received tremendous interest and feedback from our customers, and we have been listening. This is the first of a series of product introductions that expands and improves the capability of RSC's track and hold product line," said M.J. Choe, manager of the RSC's mixed-signal product engineering department.

An evaluation kit (EVRTH011) is available for performance testing of the packaged RTH011. Information about this and other high-speed data conversion products, including ADCs, DACs, and DDFSs, can be found at http://www.rockwellscientific.com/highspeed/.> Rockwell Scientific Company (RSC) is an independent, privately owned high-technology company with unique technical strengths in electronics, imaging sensors, information sciences, materials, and optics and offers complete custom design services, as well as its own family of high-performance mixed signal products. Its activities include research and development for the U.S. Government and private sector companies, manufacture and sale of specialty products, and licensing of IP, all closely tied to its R&D efforts.
