FN7405
Dual Channel Differential DSL Line Driver
for Centillium Maximus CO Chipsets
Features
• 450mA output drive capability
• 44.1V differential output drive into 100Ω
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.
• High slew rate of 500V/µs
• Bandwidth - 46MHz
• Current control pins
• Channel separation
- 80dB @ 500kHz
- 75dB @ 1MHz
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.
Applications
• ADSL line drivers for Centillium Maximus CO chipsets

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
