DS2141AQ/T&R

Telecom Overview

The DS2141AQ/T&R is a comprehensive, software-driven T1 framer designed to operate as a slave or coprocessor to a microcontroller. It supports D4, ESF, and SLC-96 framing formats with onboard dual two-frame elastic store slip buffers for jitter attenuation. The device features a parallel control port for quick access, allowing a single microprocessor to manage multiple T1 lines efficiently. It extracts and inserts robbed-bit signaling and includes FDL support circuitry. Operating on a 5V supply with low-power CMOS technology, the component is available in a 40-pin DIP package.

Telecom Procurement Notes

Verify the specific ordering suffix against official Analog Devices documentation to confirm package type and tape-and-reel specifications. Confirm that the component meets all applicable regulatory standards required for your deployment environment before finalizing procurement orders.

Telecom Selection Notes

Select this component when a software-configurable T1 controller is required alongside external line interface devices. Ensure the host system provides a compatible multiplexed address/data bus. Verify that the application requires the specific framing modes supported by this integrated circuit.

Telecom Part Context

This component belongs to the DS2141A family of T1 controllers manufactured by Analog Devices / Maxim Integrated. It is specifically engineered to handle T1 serial stream framing and unframing tasks while providing extensive status monitoring and error detection capabilities for telecommunications applications.

Telecom Replacement Considerations

Consult official manufacturer cross-reference lists for verified substitutes. Do not assume functional equivalence with other T1 framers without verifying register compatibility and pinout alignment.
