Dual Channel CO ADSL2+ Line Driver
Features
The EL1537B is a very low power dual channel differentiated
amplifier designed for central office line driving for DMT
ADSL solutions. This device features a high drive capability
of 400mA while consuming only 7.5mA of supply current per
amplifier from ±12V supplies. This driver achieves a typical
distortion of less than -75dBc, at 1MHz into a 50Ω load. The
EL1537B is available in the thermally-enhanced 28 Ld
HTSSOP package. This device is specified for operation
over the full -40°C to +85°C temperature range.
• Drives 400mA at 16VP-P on ±12V supplies
The EL1537B has two control pins, C0 and C1, per channel.
With the selection of C0 and C1, the device can be set into
full-IS power, 3/4-IS power, 1/2-IS power, and power-down
disable modes. The EL1537B maintains excellent distortion
and load driving capabilities even in the lowest power
settings. The EL1537B has extended bandwidth and
improved THD and slew rate for ADSL2+ and VDSL
applications.
• 44VP-P differential output drive into 100Ω
• 37.2VP-P minimum differential output drive into 60Ω
• -75dBc typical driver output distortion driving 50Ω at 1MHz
and 1/2-IS bias current
• Low quiescent current of 4.75mA per amplifier in 1/2-IS
mode
• 50MHz BW at AV = 10
• Power-down disable mode
• Pin-to-Pin replacement for EL1527
• Pb-free plus anneal available (RoHS compliant)
Applications
• ADSL, ADSL2, ADSL2+ line drivers
• G.SHDSL, HDSL2 line drivers
Ordering Information
• VDSL line drivers

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.
