Ordering Information
• High slew rate of 500V/µs
S+ 10
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.
• -85dBc THD @ 1MHz 2VP-P
23 C0AB
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.
• 44.1VP-P differential output drive into 100
CD 9
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.
• 450mA output drive capability
24 C1AB
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.

NOTE: Intersil Pb-free products employ special Pb-free material sets;
molding compounds/die attach materials and 100% matte tin plate
termination finish, which are RoHS compliant and compatible with both
SnPb and Pb-free soldering operations. Intersil Pb-free products are MSL
classified at Pb-free peak reflow temperatures that meet or exceed the Pbfree requirements of IPC/JEDEC J STD-020C.
