Thesys Announces 500MHz 2.5 mWatt Output ASK and FSK Transmitter ICs.LAS VEGAS--(BUSINESS WIRE)--Nov. 20, 1996--Thesys Microelectronics, the German ASIC (Application Specific Integrated Circuit) Pronounced "a-sick." A chip that is custom designed for a specific application rather than a general-purpose chip such as a microprocessor. and ASSP (Application Specific Standard Part) An ASIC chip that is designed as a generic device for a particular market. Whereas an ASIC is typically used only by its creator, ASSPs are used by many different companies in the design of their products. See ASIC. supplier, unveiled today two new 2.5 milliwatt mil·li·watt n. Abbr. mW A unit of power equal to one thousandth (10-3) of a watt. Noun 1. milliwatt - a unit of power equal to one thousandth of a watt Transmitter ICs. Called the TH7101 and TH7106, the new Thesys products are complete amplitude shift keying (ASK) and frequency shift keying (FSK (Frequency Shift Keying) A simple digital modulation technique that uses two frequencies for 0 and 1. See frequency modulation. ) transmitters respectively. Offering an extremely high level of integration, only a single external crystal and a few passive components are required for a complete transmitter solution. The chips offer cost savings and performance advantages over conventional solutions based on SAW (Surface Acoustic Wave A surface acoustic wave (SAW) is an acoustic wave traveling along the surface of a material having some elasticity, with an amplitude that typically decays exponentially with the depth of the substrate. ) filters. The TH7101 and TH7106 operate over a broad range of frequencies, from 300 to 500MHz, covering the unlicensed bands in the U.S.A., Europe and Japan. Users of these frequencies do not require any kind of license to transmit, providing they conform to certain power and spurious emission requirements. The devices meet all major standards covering these requirements, including the FCC (1) (Federal Communications Commission, Washington, DC, www.fcc.gov) The U.S. government agency that regulates interstate and international communications including wire, cable, radio, TV and satellite. The FCC was created under the U.S. Regulations Part 15 for the U.S. and the ETSI (European Telecommunications Standards Institute, Sophia Antipolis technical park, Nice, France, www.etsi.org) A non-profit membership organization founded in 1988, dedicated to standardizing information and communication technologies (ICT) throughout Europe. I-ETS I-ETS Interim European Telecommunications Standard (also seen as IETS) 300-220 specification for European use. Typical applications include keyless entry systems for cars and garages, cordless sensors for alarm systems, and remote telemetry for utility meter reading. The TH7101 and TH7106 embody many improvements over conventional SAW-based solutions. For example, they operate over a wide range power -- from below 2.7V to over 5.0V, and deliver over 2.5mW into a typical antenna load. The output frequency tolerance can be set to within +/-10kHz; an order of magnitude A change in quantity or volume as measured by the decimal point. For example, from tens to hundreds is one order of magnitude. Tens to thousands is two orders of magnitude; tens to millions is three orders of magnitude, etc. better than conventional SAW resonator resonator /res·o·na·tor/ (rez´o-na?ter) 1. an instrument used to intensify sounds. 2. an electric circuit in which oscillations of a certain frequency are set up by oscillations of the same frequency in another . This allows use of a narrow band receiver either to increase range or decrease transmitter output power -- or a combination of the two. Furthermore, the TH7101 and TH7106 meets all major worldwide standards with a single component type. This simplifies ordering and stock control for manufacturers. Compared to other IC solutions, the TH7101 and TH7106 require the fewest number of external components of any transmitter product offering this level of output power. By integrating the VCO completely within the device, it removes the need for external inductors and varactors. External inductors can give rise to coupling problems with the antenna. The TH7101 and TH7106 eliminate this risk and its associated manufacturing problems entirely. Output power is programmable via an external resistor. Richard Lodge, Product Manager responsible for Thesys' low power radio transmitters said, "After seeing prototypes, customers are very enthusiastic about the performance and cost benefits of these new parts. They're also really easy to use since the product can be supplied in a complete ready-to-copy kit, with an evaluation board and antenna. This means that even customers who have little or no RF experience can get their applications up and running immediately with a known level of performance." The TH7101 ASK and TH7106 FSK transmitters and evaluation kits are available in sample quantities now with production available in early 1997. Pricing is from $1.45 in quantities of 100k in 16-pin SOP packages. Thesys Microelectronics (Thesys Gesellschaft fur Mikroelektronik mbH) was founded in October 1992 to manufacture and market proprietary application-specific integrated circuits (ASICs) and application-specific standard products (ASSPs), as well as to provide silicon foundry services. The company offers capabilities ranging from standard circuit design to the development of complete system solutions. The firm is headquartered in Erfurt, Germany, and currently employs 420 people. Sales representation throughout Europe, USA and Asia is provided through a combination of sales offices, representatives and joint ventures. -0- Note To Editors: Thesys announced that AMS AMS - Andrew Message System (Austria Mikro Systeme AG) of Graz, Austria acquired a majority ownership in the company in 1995.
