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 IADJ pin. Two other pins (C0 and 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 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.
