Burr-Brown Introduces Industry-First Dual Analog Front End for HDSL Applications.TUCSON, Ariz.--(BUSINESS WIRE)--May 7, 1999-- Burr-Brown Corporation (NASDAQ NASDAQ in full National Association of Securities Dealers Automated Quotations U.S. market for over-the-counter securities. Established in 1971 by the National Association of Securities Dealers (NASD), NASDAQ is an automated quotation system that reports on :BBRC BBRC Biochemical and Biophysical Research Communications BBRC Bellevue Breakfast Rotary Club (Washington state) BBRC Ball Brothers Research Corporation ) today announced the AFE (Apple File Exchange) An earlier Macintosh utility that converted data files between Mac and PC formats. It also included a file translator between IBM's DCA format and MacWrite. 2124, a dual analog front end (AFE) which increases reliability, reduces component count, and lowers manufacturing costs in DSL DSL in full Digital Subscriber Line Broadband digital communications connection that operates over standard copper telephone wires. It requires a DSL modem, which splits transmissions into two frequency bands: the lower frequencies for voice (ordinary (Digital Subscriber Line See DSL. (communications, protocol) Digital Subscriber Line - (DSL, or Digital Subscriber Loop, xDSL - see below) A family of digital telecommunications protocols designed to allow high speed data communication over the existing copper telephone lines between end-users and ) applications. DSL technology provides high-speed Internet data transfer using existing copper wire infrastructures. The vast network of copper wire telephone lines, more than 600 million lines worldwide, makes DSL an attractive alternative to other high-speed data transfer technologies. The AFE2124 is optimized for HDSL See DSL. HDSL - High bit-rate Digital Subscriber Line (High bit rate DSL) applications, the most widely used DSL technology. HDSL is ideal for business oriented T1/E1 data transfer services as well as local area network extenders and Internet servers. In these applications, the AFE2124 provides all the analog circuitry, including drivers, needed to connect two HDSL digital signal processors to line transformers. "The dual AFE2124 replaces standard two-chip designs with a single chip solution. As a result, this chip reduces system complexity, lowers handling cost, and increases reliability," said CR Teeple, DSL strategic marketing manager at Burr-Brown. "In addition to the advantages gained from single chip integration, the AFE2124 features low power dissipation of 250mW per channel and low cost-per-channel." Teeple added: "The AFE2124 enhances our position as the leading supplier of analog front ends for DSL applications." Functionally, each half of the dual AFE2124 consists of a transmit and receive section. The transmit section generates and filters analog signals to create 2B1Q symbols. The receive section filters and digitizes the symbol data received on the telephone line. An on-board differential line driver provides a 13.5dBm signal to the telephone line. Features include scaleable data rate (64kbps to 1168kbps operation), transmit power boost, and single 5V supply operation. The AFE2124 is priced from $18.00 in 1,000s and housed in a 48-pin SSOP SSOP Shrink Small Outline Package SSOP Sanitation Standard Operating Procedures (USDA) SSOP Sanitary Standard Operating Procedures SSOP Sharescan-Open Platform (Ecopy) SSOP Site Security Operational Procedures package. Delivery is from stock.
