A telecom line interface IC for central office (CO) and customer premise equipment (CPE) applications in the telecom sector is the ISL5585 from Renesas Electronics America Inc. The highest differential DC error for this IC, which offers exceptional accuracy performance under a variety of operating circumstances, is just 0.1%.
The ISL5585 may function in a variety of telephone systems thanks to its wide input voltage range of 200V. In order to avoid overstressing CO/CPE wires, it also has programmed loop current limitation. Additionally, the ISL5585 is made to consume as little power as possible; its usual power dissipation is only 25mW.
Numerous telecom applications, including line cards, customer premises equipment (CPE), set-top boxes, and devices that link to the public switched telephone network (PSTN), use this high-accuracy and adaptable telecom line interface IC. The ISL5585 is the perfect option for space-constrained telecom equipment designs thanks to its small 20-pin SSOP packaging.
