Elantec Introduces Industry's First Monolithic Dual Port DSL Line Driver: Leading-Edge Driver Features Low Power, Small Footprint, And Low Cost

New EL1528C, designed for Central Office equipment, DSLAM cards, simplifies line driver section of DSL systems

MILPITAS, CALIFORNIA, May 8, 2002 -- Elantec Semiconductor, Inc. (NASDAQ: ELNT), a leader in high-performance analog ICs, today announced the industry’s first commercially available monolithic dual port DSL line driver for high density Central Office (CO) applications. The EL1528C is the latest addition to Elantec’s family of line drivers, which deliver lower power, lower cost, and a smaller footprint with each successive generation.

The new EL1528C uses proprietary circuitry to achieve very low distortion and 675mW/port, total power consumption in full rate ADSL applications. Available in a tiny 4mm x 5mm LPP package, the EL1528C reduces DSL line driver power by eight to 15 percent. It also reduces package footprint by 30 to 50 percent, compared with its predecessors, the EL1507C and EL1508C.

The EL1528C is a class A/B amplifier intended for designs requiring only two rails with +/- 12V supply voltages and up to 450mA drive current. The EL1528C output swing is improved to 44.4Vp-p differential while driving 100 ohms. This increased output swing can help reduce cyclical redundancy check (CRC) errors at reduced power dissipation.

The EL1528C is the first commercially available monolithic dual port driver. At 10mm sq/port it offers the industry’s smallest footprint for DSLAM line card designs. The device is made using Elantec’s high-voltage silicon-on-insulator process (SOI), and applies proprietary circuitry to achieve excellent channel separation of –85dB, typical.

The EL1528C is a sixth generation current mode feedback DSL driver. It has been optimized for low power, ease-of-use and requires a limited number of external components. As a result, the EL1528C requires up to 11 fewer external components per port than other voltage feedback line drivers need. This is a significant design and cost advantage.

The combination of lower power, smaller footprint, and the reduction in external components enables the design of leading edge, very high port count DSL line cards. Higher port counts per square inch help reduce cost and improve profitability for DSLAM vendors.

“Once again Elantec has introduced a leadership line driver for the DSL industry. The EL1528C has been well received by DSLAM manufacturers for its reduced cost, lower bill of materials and lower power advantages,” said Kaveh Parsi, Director of Marketing for Communications Products. “Elantec is committed to developing new products for Central Office and Customer Premise applications that will further integrate and simplify the line driver section of the DSL system.”

The EL1528C will be available in production quantities in June at a price of $4.35 each in 1,000-piece units.
