Clare's Next Generation All-Silicon Data Access Arrangement With On-Chip Isolation Now Available.Business Editors/High-Tech Writers BEVERLY, Mass.--(BUSINESS WIRE)--Feb. 12, 2001 LITELINK II Features Optimum Supply Voltage Operation For Interfacing With Wide Array of Modem and CODEC Chipsets Clare, Inc. (Nasdaq:CPCL CPCL Chennai Petroleum Corporation Limited CPCL Computer Program Change Library CPCL Computer Program Control Library CPCL Component Prioritized Collection List ), a leading provider of integrated silicon solutions for reliable connectivity to the last inch of the last telecommunications mile, today announced immediate availability of the industry's first, single package data access arrangement (DAA DAA - Distributed Application Architecture: under design by Hewlett-Packard and Sun. A distributed object management environment that will allow applications to be developed independent of operating system, network or windowing system. ) that includes an isolation barrier inside the chip. Designers can now use Clare's LITELINK II DAA (Part No. CPC (1) (Central Processing Complex) An IBM mainframe that has two or more central processors (CPs) that share memory. It is the collection of processors, memory and I/O subsystems manufactured with a single serial number, typically all contained in one cabinet. 5610A) as a replacement for bulky magnetic transformers and various other discrete components commonly found in traditional DAAs. The LITELINK II DAA enables minimized board space, reduced product In model theory, a branch of mathematical logic, the reduced product is a construction that generalizes both direct product and ultraproduct. costs and a simplified manufacturing process in modem, set-top box The cable TV box that sits on "top" of the TV "set," although it is often located several feet away in an equipment rack. The set-top box descrambles the premium channels and provides a tuner for the higher cable numbers that very old TVs did not support. and telephony applications. Clare's all-silicon DAA features 2.7V to 5.5V operation to provide designers with unmatched flexibility and compatibility for interfacing with popular modem and voice band CODEC chipsets. In addition, the LITELINK II solution offers the simplest system for international compatibility with the publicly switched telephone network (PSTN (Public Switched Telephone Network) The worldwide voice telephone network. Once only an analog system, the heart of most telephone networks today is all digital. In the U.S. ). Clare's LITELINK II has been successfully tested to UL1950, UL1459, UL1577, EN60950, 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. Part 68 and Part 15, and TBR-21. "LITELINK II is an ideal solution for telephony gateways to the 'New Generation Networks' as well as conventional circuit-switched access systems," said Mark Elder, president of Aztek Engineering. "The simplicity and modest space requirements inherent in LITELINK II-based designs make it an excellent choice for these applications." "The high levels of integration we have achieved in the design of our LITELINK II DAA has a number of direct benefits to our customers," said Steve Andrezyk, director of marketing for CPE (Customer Premises Equipment) Communications equipment that resides on the customer's premises. CPE - Customer Premises Equipment products, Clare, Inc. "It replaces numerous components including the bulky isolation transformer of a discrete DAA and at the same time can be easily interfaced with popular modem and CODEC chipsets." Compact Design and On-chip Isolation Barrier Dramatically Minimize Board Space Clare's distinctive design of the LITELINK II places a 1500VRMS VRMS Virtual Richard M. Stallman (software package) VRMS Volts Root Mean Square VRMS Volt Root Mean Square isolation barrier between the line side and modem side integrated circuits (IC) located inside the small 32-pin SOIC (Small Outline IC) A small-dimension, plastic, rectangular, surface mount chip package that uses gull-wing pins extending outward. See gull-wing lead, SOJ and chip package. package. This eliminates the need for external optocouplers or high-voltage capacitors in the data path. The tiny .30" x .38" x .08" package contains two optically isolated data transmission paths between the line side and modem side circuits. Clare's long history and expertise in optical coupling have enabled the innovative design and advanced manufacturing of this DAA. Clare's LITELINK II DAA offers a broad feature set, including high-voltage isolation, proper AC and DC phone line terminations, 2-to-4 wire hybrid function, on-hook and off-hook detection, caller ID, and half wave ring detect circuitry. For European countries that use battery reversal to indicate the transmission of caller id information, the LITELINK II is available with full wave ring detection as the CPC5611A. Additional LITELINK II Products Clare also offers a user programmable driver IC (Part No. CPC5601D) to provide the simplest system for international compatibility. This IC provides an optically coupled single pin serial port interface that can be programmed to work with any PSTN. The CPC5601D is programmed by inputting a bit stream directly into the serial interface and can be controlled by either the host or the user. In addition, Clare offers a companion N-Channel Depletion Mode high voltage FET FET: see transistor. (Field Effect Transistor) One of two major categories of transistor; the other is bipolar. FETs use a gate element that, when charged, creates an electromagnetic field that changes the conductivity of a silicon (Part No. CPC5602C) that acts as a linear regulator for the DAA over a wide range of phone line voltages. The CPC5602C has been specifically designed to provide the necessary performance to meet applicable telecom requirements for real-world line conditions at the lowest possible cost. All LITELINK product enhancements are available and can be ordered by their respective part number. Pricing and Availability The LITELINK (CPC5610/5611) is now available in production OEM (Original Equipment Manufacturer) The rebranding of equipment and selling it. The term initially referred to the company that made the products (the "original" manufacturer), but eventually became widely used to refer to the organization that buys the products and quantities of 25,000 and is priced at $2.79 with a standard lead-time of 8 weeks after receipt of order.
