xDSL Differential Line Driver
The EL1517B is a dual operational amplifier designed for VDSL
and ADSL line driving in DMT based solutions. EL1517B
includes internal protection for high ruggedness against
lightning related transients. This device features a high drive
capability of 250mA while consuming only 7mA of supply
current per amplifier and operating from a single 5V to 12V
supply. This driver achieves a typical distortion of 80dBc, at
150kHz into a 25Ω load. The EL1517B is available in a
10 Ld HMSOP package and is specified for operation over the
full -40°C to +85°C temperature range. The device has control
pins C0 and C1 for controlling the bias and enable/disable of
the outputs. These controls allow for lowering the power to fit
the performance/power ratio for the application.
The EL1517B is ideal for ADSL, SDSL, HDSL2 and VDSL line
driving applications. All performance graphs in this datasheet
were generated for EL1517BIS and EL1517BIL. There is no
significant electrical difference between EL1517BIYE and the
performance curves for EL1517BIL.
The EL1517B can only be used for single supply operation.
Use EL1517BIL or EL1517BIS for dual supply applications.

NOTE: Intersil Pb-free plus anneal 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.
