Dual Channel Differential DSL Line Driver
Features
The ISL1533 is a dual channel differential amplifier designed
for driving full rate ADSL2+ signals at very low power
dissipation. The high drive capability of 450mA makes this
driver ideal for DMT designs. It contains two pairs of
wideband, high-voltage, current mode feedback amplifiers
designed on Intersil’s HS30 Bipolar SOI process for low
power consumption in DSL systems. This process also
provides for very rugged protection against lightning induced
surges on the line.
• 450mA output drive capability
These drivers achieve an MTPR distortion measurement of
better than 70dB, while consuming typically 5mA per DSL
channel of total supply current in 1/2 IS mode. 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 preset modes (full-IS, 3/4-IS, 1/2-IS, and full
power-down). The ISL1533 integrates 50k pull-up resistors
on C0 and C1 pins to initially disable the device.
The ISL1533 operates on ±5V to ±15V supplies and retains
its bandwidth and linearity over the complete supply range.
