ISL1539A
Dual Port VDSL2 Line Driver
The ISL1539A provides 4 internal wideband op amps intended to be used as two pairs of differential line drivers. The ISL1539A’s high bandwidth, 240MHz, and ultra low distortion, -89dBc @ 1MHz, 2VP-P, support the demanding MTPR requirements of emerging VDSL2 line driver designs. Less demanding requirements can be met at very low quiescent powers using the supply current adjustment features.
Each of the 4 internal op amps is a wideband current feedback amplifier offering very high slew rate intrinsic to that design using low quiescent current levels. Each of the two pair of amplifiers (ports) can also be power optimized to the application using two external quiescent control logic pins. Full power is nominally 27.
