ISL1591IRTZ-EVALZ規(guī)格書詳情
The ISL1591 provides 4 internal wideband op amps intended
to be used as two pairs of fixed gain differential line drivers.
The ISL1591’s high bandwidth, and ultra low distortion
enables the support of VDSL2 8b, 17a, and 30a in central
office modem applications. This highly versatile line driver
allows for operation from +14V to +24V nominal power
supplies, while delivering exceptional MTPR distortion
performance.
Using a single +24V supply, the ISL1591 MBPR distortion is
below -62dBc in VDSL2 8b, -63dBc in VDSL2 17a, and -60dBc
in VDSL2 30a profiles. Using a single +14V supply, ISL1591
supports 14.5dBm VDSL2 17a and 30a profiles at only a
power consumption of 425mW. This capability is ideal for
short loop, high bit rate VDSL2 applications where 14.5dBm
transmit power is all that is required. For full power VDSL2 8b
profile with 20dBm of transmit power, the line driver will
require +24V single supply.
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 14mA/port with options of medium power
cutback to 9.7mA/port, a low power condition at 7.4mA/port,
and an off state at <0.5mA/port.
High power push/pull line driver applications are best
supported using a low headroom, high output current device.
On +24V supplies, the ISL1591 offers a 1.6V headroom with
>360mA peak output current. Driving differentially, this gives
>42.4VP-P swing to as low as 58Ω differential load. The four
amplifiers in ISL1591 are intended to be used as differential
pairs and not as individual amplifiers.
