VDSL2 line driver in small QFN Package

Intersil Corporation has launched its ISL1539, the latest addition to Intersil’s family of line drivers featuring low power, very small footprint and good linearity. The ISL1539 is the first monolithic, dual port, DSL line driver for 100Mbps VDSL2 Central Office (CO) applications.

The ISL1539 uses proprietary circuitry to achieve low distortion, high capacitance drive and less than 910mW/port total power consumption while delivering 20.5dBm output power in 5-band VDSL2 applications. This driver uses Intersil’s own new high speed bipolar process technology to extend the performance of ADSL2, ADSL2+ and VDSL2 bandwidth high voltage line drivers.

The ISL1539 is a performance extension of Intersil’s ADSL2+ line drivers, thus this new driver supports full ADSL2+ fall back capability to drive long loop lengths at lower data rate as well as shorter loops at the full 100Mbps rates.

The ISL1539 enables designers to achieve very high port count VDSL2 line cards aimed at IP TV and video on-demand service applications. The dual port drivers are packaged in a tiny 4x5mm QFN package allowing the smallest footprint for VDSL2 applications. Low bias current, ease of use for high density PCB layout and a reduced number of external components provide unmatched performance and footprint features.
