ISL1591
ISL1591 is VDSL2 Line Driver manufactured by Renesas.
Fixed Gain, Dual Port, VDSL2 Line Driver
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 -62d Bc in VDSL2 8b, -63d Bc in VDSL2 17a, and -60d Bc in VDSL2 30a profiles. Using a single +14V supply, ISL1591 supports 14.5d Bm VDSL2 17a and 30a profiles at only a power consumption of 425m W. This capability is ideal for short loop, high bit rate VDSL2 applications where 14.5d Bm transmit power is all that is required. For full power VDSL2 8b profile with 20d Bm of transmit power, the line driver will require +24V single supply.
