IS31CG1110-QFLS2-TR

Overview

The IS31CG1110-QFLS2-TR is a high-performance MIMO/SISO dual-port differential line driver designed for broadband Power Line Communication (PLC) systems. It integrates two pairs of wideband, high-voltage current mode feedback amplifiers operating on a single +10V to +13.2V supply. The device features a fixed voltage gain of 25dB (Av=18 V/V), a 100MHz -3dB closed-loop signal bandwidth, and a maximum output driver capability of 350mA. It supports TDM operation via separate enable pins, includes internal input common-mode generation, and provides thermal shutdown protection at approximately 165°C.

Feature Summary

Dual-port architecture with independent enable controls for flexible MIMO or SISO configurations
High linearity performance with a Multi-Tone Power Ratio (MTPR) of 50dBc
Integrated thermal shutdown circuitry to protect against overheating
Internal input common-mode generator to maximize dynamic range

Applications

Broadband Power Line Communications (PLC)
Smart Grid applications
Smart Home systems including IPTV and security cameras
High voltage and high current driving circuits

Procurement Notes

Verify the component status as preliminary in official documentation before finalizing designs. Confirm that the QFN-20 package dimensions and thermal pad requirements align with PCB layout capabilities. Ensure supply voltage constraints between +10V and +13.2V are strictly maintained within the application circuit design parameters.

Selection Notes

Select this driver for applications requiring high-speed differential signaling over power lines. The fixed 18 V/V gain simplifies external resistor networks. Consider the 4mmx4mm QFN-20 package size for space-constrained layouts. Evaluate thermal management needs given the junction temperature limits and ambient operating range specifications.

Part Context

This component belongs to Lumissil Microsystems' CG series of line drivers. It is specifically engineered for broadband PLC environments where high linearity and wide bandwidth are critical. The device replaces discrete amplifier solutions by integrating dual ports into a compact thermally enhanced package.
