LE87511NQCT

Telecom Overview

The LE87511NQCT is a single-channel line driver from Microchip Technology's BD870 series, designed for G.hn power line communication systems. It utilizes Microsemi's HV30 Bipolar SOI process to achieve low power consumption with wideband amplifiers. The device features fixed internal gain of 25 dB and operates up to 86 MHz. It supports Class AB operation and can drive line impedances between 50 Ω and 200 Ω. Powered by a single supply, it offers four preset bias levels for optimization. The component is housed in a small 16-pin, 4x4 mm QFN package.

Telecom Feature Summary

• Single-channel architecture optimized for home network G.hn power line communication applications
• Integrated enable/disable control to force low-power high-impedance mode during receive transmissions
• Configurable bias levels allowing optimization of power consumption versus performance metrics

Telecom Applications

• Power Line Communications (PLC) systems
• Home networking infrastructure
• HPNA (Home Phoneline Networking Alliance) interfaces
• G.HN standard compliant devices

Telecom Procurement Notes

Verify the specific ordering suffix against official documentation to confirm shipping configuration. The LE87511NQCT designation indicates a tape and reel packaging format, distinct from tray options. Confirm RoHS compliance status and moisture sensitivity levels prior to assembly planning. Ensure compatibility with the required 16-pin QFN footprint on the target PCB layout.

Telecom Selection Notes

Select this component for designs requiring a single-channel driver with fixed gain characteristics. Evaluate the 25 dB gain and 86 MHz bandwidth against system requirements. Consider the single-supply operation and available bias settings for power management strategies. Verify that the 50 Ω to 200 Ω drive capability matches the target power line impedance environment.
