ISL1561IRZ Dettagli del prodotto

The ISL1561 is a fixed gain dual port class-G differential
amplifier designed for driving full rate ADSL2+ and VDSL2
signals at very low power dissipation. The driver runs on a
single +14V power supply and internally generates higher
supply voltages when needed to enable power efficient
operation for high peak-to-average ratio (PAR) ADSL2+ and
VDSL2 signals.
In ADSL2+ mode of operation with full 19.8dBm transmit
signal power across 100Ω line load, each port consumes only
520mW of power, while with 19.5dBm VDSL2 8b profile a port
consumes 610mW of power. In VDSL2 17a mode of operation
with 14.5dBm transmit power, a port will consume 411mW of
power. These typical power consumption figures account for
receiver hybrid loading effects and transformer losses.
The ISL1561 provides two ports of wideband, current feedback
amplifiers optimized for low power consumption in xDSL
systems. The drivers achieve an average upstream missing
band power ratio (MBPR) distortion of better than -64dBc
under 19.8dBm transmit signal power into 100Ω load. A three
pin serial interface is used to program an 8-bit internal register
to set each port’s supply current with 0.5mA step size. This
flexibility allows the DSP to optimize each port separately
during modem training.
The device is supplied in a thermally-enhanced small footprint
(4mmx4mm) 24 lead QFN package. The ISL1561 is specified
for operation over the full -40°C to +85°C industrial
temperature range and is Pb-free RoHS compliant.

Features
• Internal fixed gain of 11.6V/V to transformer (see Figure 3)
• 360mA output drive capability
• 41.8VP-P differential output drive into 100Ω in class G mode
• VDSL2 8b profile MTPR of -64dBc
• VDSL2 17a profile MTPR of -60dBc
• ADSL2+, VDSL2 8b and 17a power consumption of 520mW,
610mW and 411mW respectively
• 8-bit programmable register to set supply current on each
port
• 3 pin serial port interface

Applications
• Dual port ADSL2+ and VDSL2 DSLAM
