Dual Channel Fixed Gain Differential DSL
Line Driver
The ISL1534 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. The amplifiers have an
internal fixed gain, which helps eliminate both feedback and
gain resistors reducing board size and cost.
These drivers consuming typically 4mA per DSL channel of
total supply current at 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 pre-set modes (full IS, 3/4 IS, 1/2 IS, and full powerdown). C0 and C1 inputs are design to pull high initially.
Floating these inputs will put the device in disable mode.
This is contrary to EL1528 where C0 and C1 inputs pull low
initially and is in the enable state when C0 and C1 pins are
floated.
The device is supplied in a thermally-enhanced small
footprint (4mmx5mm) 24 Ld QFN and a 20 Ld HTSSOP
packages. The ISL1534 is specified for operation over the
full -40°C to +85°C temperature range.
The ISL1534 provides larger output swing at heavy loads,
higher slew rate, and higher bandwidth while maintaining
pin-to-pin drop-in compatibility with the ISL1532A. The
ISL1534 integrates 50k pull-up resistors on C0 and C1 pins.
