ISL1539IRZ Datasheet, PDF (1/11 Pages) Intersil Corporation – Dual Channel Differential VDSL2 Line Driver

Dual Channel Differential VDSL2 Line Driver
ISL1539
The ISL1539 is to be used for high performance long reach
and high speed applications, including ADSL2, ADSL2+, and
VDSL2 20dBm.
The ISL1539 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 -60dB MTPR @ 1.1MHz, while
consuming typically 10mA per DSL channel of total supply
current. This supply current can be set using a resistor on the
I_ADJ pin. Two other pins (C₀ and C₁) 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 ISL1539 operates on ±5V to
±15V supplies and retains its bandwidth and linearity over the
complete supply range.
The device is supplied in the small footprint (4mmx5mm) 24 Ld
QFN package and is specified for operation over the full
-40°C to +85°C temperature range.

NOTES:
1. Please refer to TB347 for details on reel specifications.
2. These Intersil Pb-free plastic packaged products employ special Pb-
free material sets, molding compounds/die attach materials, and
100% matte tin plate plus anneal (e3 termination finish, which is
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.
3. For Moisture Sensitivity Level (MSL), please see device information
page for ISL1539. For more information on MSL, please see tech
