  • Product Introduction

Key features:

Fixed gain internally at R load 11.6V/V ± 360mA output drive capability 42.4V P-P differential output driven to 82.6Ω -62dBc MBPR (Introduction to 8B by VDSL) - US1 65dBc, -63dBc, 1686 MBPR (17A profile for VDSL2) US1-64dBc-62dBc 1686, US3 MBPR for -60dBc (30A Profile for VDSL) High conversion rate of 2000V/μs differential equations Bandwidth (170MHz) Power current control pin K.20, GR-1089 Surge Robustness Verification Lead-free (RoHS compliant) description

ISL1591提供了4个内部宽带运算放大器拟对两个固定增益差分线路驱动器的使用。ISL1591s高带宽，超低失真，使VDSL2的8B，17A，30A在中央办公室调制解调器应用的支持。这种高度灵活的线路驱动器，可以从+14 V到+24 V的标称电源的操作，同时提供出色的MTPR失真性能。使用单一的+24 V电源，的ISL1591 MBPR的失真低于-62dBc的VDSL2 8B，-63dBc的VDSL2 17A，和-60dBc的在VDSL2 30A配置文件。使用单一的+14 V供电，ISL1591支持14.5dBm的VDSL2 17A和30A型只有425mW的功耗。这种能力是短循环，高比特率14.5dBm发送功率是所有需要VDSL2应用的理想选择。全功率的VDSL2 8B轮廓与20dBm的发射功率，线路驱动器将需要+24 V单电源供电。4内部运算放大器是宽带电流反馈放大器，提供非常高的压摆率，设计采用低静态电流水平的内在。每两对放大器（端口），也可以优化应用程序使用两个外部静态控制逻辑引脚的电源。全功率名义上14mA/port选项中等功率削减到9.7mA/port，低功耗的条件下，在7.4mA/port和在360毫安峰值输出电流的净空。驾驶的差异，这给58Ω差分负载低> 42.4V 聚丙烯摆动。ISL1591的四个放大器拟用于差分对，而不是作为单独的放大器
