Burr-Brown Introduces High-Speed, High-Output Line Driver for DSL Communications Systems.Business Editors/High-Tech Writers TUCSON, Ariz.--(BUSINESS WIRE)--May 1, 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 OPA2677, a high-speed, dual operational amplifier designed specifically for 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 (DSL) driver applications. The OPA2677 achieves the high power output required in emerging ADSL See DSL. ADSL - Asymmetric Digital Subscriber Line (Asymmetrical DSL) and HDSL See DSL. HDSL - High bit-rate Digital Subscriber Line 2 (High bit rate DSL 2) communications systems. "The OPA2677 represents the industry's leading high-performance/low-price solution for ADSL upstream and HDSL2 line driver applications," said Michael Steffes, strategic marketing manager for high-speed signal processing products at Burr-Brown. "The OPA2677's 500mA output and 10Vpp output swing far exceed the typical requirements of +12V DSL line driver systems, giving considerable design margin for less than ideal real world conditions." DSL technology offers high-speed Internet data transfer using existing copper-wire telephone lines. With over 900 million lines worldwide, DSL is the fastest growing broadband communication technology. The OPA2677 was designed using Burr-Brown's internal Complementary Bipolar CMOS (Complementary Metal Oxide Semiconductor) Pronounced "c-moss." The most widely used integrated circuit design. It is found in almost every electronic product from handheld devices to mainframes. (CBC (1) (Cell Broadcast Center) See cell broadcast. (2) (Cipher Block Chaining) In cryptography, a mode of operation that combines the ciphertext of one block with the plaintext of the next block. ) process. CBC is a flexible, high performance mixed-signal process that uses a modular approach to meet the demands of specific applications while minimizing cost and improving design flexibility. This integrated process development gives superior price/performance to the more typical industry approach of merely "adding-on" capabilities to existing core processes. Technical Detail Operating on a single +12V supply, the OPA2677 consumes a low 9mA/channel quiescent current to deliver a very high 500mA output current. Guaranteed output current supports even the most demanding ADSL CPE (Customer Premises Equipment) Communications equipment that resides on the customer's premises. CPE - Customer Premises Equipment requirements with >280mA minimum output current and low harmonic distortion. The high 200MHz bandwidth will also support the most demanding VDSL (Very high bit rate DSL) line driver requirements. Other features include logic controlled power settings, 1800V/micro-second slew rate, and the lowest output noise available for a DSL driver. The OPA2677 is priced from $2.29 in 1,000 piece quantities and packaged in a standard SO-8 (a thermally enhanced SO-8 and a standard SO-14 will be available later in 2Q'00). Delivery is from stock.
