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

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.

Features

• 450mA output drive capability

• High slew rate of 500V/µs

• Bandwidth - 46MHz

• Current control pins

• Channel separation

- 80dB @ 500kHz

-75dB @ 1MHz

Applications

• ADSL line drivers for Centillium Maximus CO chipsets
