1 / 2 page 1 ® FN7405.1 EL1526 Dual Channel Differential DSL Line Driver for Centillium Maximus CO Chipsets The EL1526 is to be used with Centillium's 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. These drivers achieve a total harmonic distortion (THD) measurement of typically -64dB @ 2.2MHz, while consuming typically 5mA per DSL channel of total supply current. This supply current can be set using a resistor on the IADJ pin. Two other pins (C0 & C1) can also be used to adjust supply current to one of four pre-set modes (full-IS, 3/4-IS, 1/2-IS, and full power-down). The EL1526 operates on ±5V to ±12V supplies and retains its bandwidth and linearity over the complete supply range. The device is supplied in the small footprint (4x5mm) 24-pin QFN package and is specified for operation over the full -40°C to +85°C temperature range.
