Burr-Brown Introduces Dual Analog Front End for High-Speed Communications.Business Editors/High-Tech Writers TUCSON, Ariz.--(BUSINESS WIRE)--Jan. 11, 2000 Burr-Brown Corp. (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 AFE2126, a dual analog front end (AFE) which greatly reduces the size and cost of DSL (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 ) communications systems. DSL technology enables 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 AFE2126 is optimized for HDSL (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. Within HDSL applications, the AFE2126 provides the entire analog circuitry, including drivers, required to connect two HDSL digital signal processor A digital signal processor (DSP) is a specialized microprocessor designed specifically for digital signal processing, generally in real-time computing.

"By integrating two complete HDSL analog interfaces on a single chip, the AFE2126 reduces system complexity, lowers handling cost, and increases reliability when compared to two-chip solutions," said CR Teeple, DSL strategic marketing manager at Burr-Brown. "Offering the industry's only dual AFEs has, once again, extended Burr-Brown's position as the leading supplier of analog front ends for DSL applications." Technical Detail The AFE2126's low out-of-band Power Spectral Density (PSD) meets the new proposed PSD standards from ANSI (American National Standards Institute, New York, www.ansi.org) A membership organization founded in 1918 that coordinates the development of U.S. voluntary national standards in both the private and public sectors. It is the U.S. member body to ISO and IEC. (American National Standards Institute See ANSI. (body, standard) American National Standards Institute - (ANSI) The private, non-profit organisation (501(c)3) responsible for approving US standards in many areas, including computers and communications. ANSI is a member of ISO. ), as well as ETSI (Europe Telecommunications Standards Institute) requirements. Functionally, each half of the dual AFE2126 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), serial digital interface This article is about the serial digital interface used in professional video.

The AFE2126 is priced from $18.00 in 1,000 piece quantities and housed in a 48-pin SSOP package. Delivery is from stock.
