ISL1539 Overview
The ISL1539 is an integral part of the signal chain. 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. These drivers achieve a total harmonic distortion (THD) measurement of typically -60dB MTPR @ 1.1MHz, while consuming typically 10mA per DSL channel of total supply current.
