Intersil Introduces 720mW Low Power and High Fidelity Line Driver for VDSL DMT Applications
-- New EL1517 offers low power dissipation for both CO and CP VDSL line cards~-- Offers significant performance advantage when compared with integrated CMOS line driver alternatives
MILPITAS, CA, September 20, 2004 Intersil Corporation (NASDAQ: ISIL), a world leader in the design and manufacture of high performance analog solutions, today announced the availability of a new high-speed dual operational amplifier designed for use with Very-high-bit-rate Digital Subscriber Line (VDSL) and Asymmetric Digital Subscriber Line (ADSL) line driving in Discrete Multi-Tone (DMT) based solutions aimed at video-on-demand service applications. The EL1517 is the latest addition to Intersils family of xDSL line drivers optimized for low power, ease of use and a reduced number of external components and extremely good linearity.
The new EL1517 makes use of Intersils trench isolated complementary bipolar process to achieve very low distortion and less than 500 mW/port total power consumption in VDSL DMT applications. The driver has been optimized for 5-band VDSL signaling requiring high bandwidth and low distortion in the 4 MHz to 17 MHz frequency range. The EL1517 can be used for VDSL Central Office (CO) or Customer Premise (CP) applications. The device can also be used in ADSL, ADSL2+ CPE applications since it easily exceeds the requirements for these standards.
The bipolar transistor based EL1517 offers better fidelity than similar CMOS line drivers integrated in some VDSL AFEs. Since the EL1517 can be used with up to a 12 V supply rail this allows for use of transformer ratios that maintain better signal to noise ratio for the received signal as compared to CMOS solutions using 5V supply rails. This can provide higher data rates and longer reach in VDSL applications. The addition of this VDSL amplifier completes Intersils portfolio of very high performance DSL line drivers ranging from ADSL to ADSL2+ and VDSL. Offered in the tiny 16-pin 4x4 mm MLF package at 16 mm2 per port, this line driver offers the industrys smallest footprint for VDSL line card designs.
