ISL1536IRZ-T13

Overview

The ISL1536IRZ-T13 is a dual-channel, high-speed, low-power line driver designed for symmetric digital subscriber line (SDSL) and DMT ADSL2+ applications. It features an internal fixed gain of AV = 12.85 with integrated feedback resistors. The device provides a 43.4VP-P differential output drive into 100Ω and ensures a minimum differential output of 41.6VP-P. Packaged in a 16-QFN (4x4) format, it serves as a central office line driver.

Feature Summary

• Dual-channel differential amplifier architecture optimized for central office line driving
• Internal fixed gain configuration with integrated feedback resistors eliminates external components
• High differential output drive capability supporting standard 100Ω transmission lines

Applications

• Symmetric Digital Subscriber Line (SDSL) systems
• DMT ADSL2+ central office line driving
• High-speed data transmission interfaces requiring differential signaling

Procurement Notes

Verify the specific suffix T13 indicates tape-and-reel packaging when sourcing. Confirm that the IRZ designation corresponds to the industrial temperature range requirements for your deployment environment. Ensure compatibility with 16-QFN footprint specifications during PCB layout validation to prevent mechanical or thermal mismatches.

Selection Notes

Select this component for designs requiring precise fixed-gain amplification without external resistor networks. The integrated feedback structure simplifies board space constraints while maintaining signal integrity. Consider the dual-channel configuration if simultaneous independent line driving is necessary for multi-port interface implementations.
