The EL1526 is to be used with Centilliums Maximus CO chipset for very high performance ADSL applications. The line driver supports use of ADSL downstream spectrum up to 3.75MHz, beyond traditional 1.1MHz range. For the extended spectrum, payload rates up to 50Mbps is achievable in conjunction of High-Bit-Loading (HBL) feature of Maximus CO chipset. This feature allows DMT tones to carry higher than 15 bits per tone, resulting in higher performance ADSL services.
The EL1526 is an integral part of the signal chain for HBL. The driver has been optimized for flat gain response and reduced harmonic distortion and noise in the bands of interest to improve the overall signal to noise in the system. A unique internal compensation circuit eliminates the need for external common mode snubber filters in active termination applications.
