DS21Q41-BT

Telecom Overview

The DS21Q41-BT is a quad T1 framer integrated circuit manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 4.5V to 5.5V and draws a typical supply current of 30mA. The device features four independent circuits designed for telecom applications, specifically handling T1 framing tasks. It utilizes a parallel/serial interface architecture and is housed in a 128-LQFP package with dimensions of 14x20 mm.

Telecom Feature Summary

• Integrates four independent T1 framing channels for high-density telecom applications
• Supports standard parallel and serial interface protocols for system integration
• Designed specifically for processing and framing T1 signals in telecommunications networks

Telecom Applications

• Telecom network infrastructure equipment requiring T1 line interfacing
• Digital signal processing systems utilizing T1 framing standards
• Communication hardware integrating multiple T1 channels

Telecom Procurement Notes

Verify component authenticity through authorized distributors or official manufacturer channels due to potential availability constraints. Confirm package integrity and pin alignment against the 128-LQFP specification before installation. Ensure power supply stability within the 4.5V to 5.5V range to prevent operational faults. Check for obsolescence notices or lifecycle status updates from Analog Devices prior to final procurement decisions.

Telecom Selection Notes

Select this component when designing systems requiring four simultaneous T1 framing channels. Ensure the host platform supports the required 128-LQFP footprint and thermal dissipation characteristics. Verify that the system voltage rails align with the specified 4.5V to 5.5V operating window. Consider interface compatibility with existing parallel or serial control logic during the architectural design phase.

Telecom Part Context

This part belongs to the DS21Q41 series of telecom interface ICs produced by Analog Devices Inc./Maxim Integrated. It serves as a specialized solution for T1 network applications, distinct from other variants like the DS21Q59 which targets E1 standards. The series focuses on providing robust framing capabilities for digital telecommunication lines.
