EL1529
Dual Channel Differential DSL Line Driver
for Globespan CO Chipsets
The EL1529 is to be used with Globespan's G7566-850 CO
chipset for high performance long reach and high speed
applications, including ADSL2, ADSL2+, G.Span, and
G.Span+.
The EL1529 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 -70dB @ 1.1MHz, while
consuming typically 5mA per DSL channel of total supply
current. This supply current can be set using a resistor on
the I
ADJ
pin. Two other pins (C
0
& C
1
) can also be used to
adjust supply current to one of four pre-set modes (full-I
S
,
3/4-I
S
, 1/2-I
S
, and full power-down). The EL1529 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.

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 Pb-free requirements of IPC/JEDEC J STD-020.
