DS2141AQ

Telecom Overview

The DS2141AQ is a T1 controller manufactured by Analog Devices Inc./Maxim Integrated, packaged in a 44-pin PLCC (16.59x16.59 mm) surface-mount format. It operates on a single 5V supply with a current consumption of 10mA and supports an operating temperature range of 0°C to 70°C. The device features a parallel control port for microprocessor interfacing, onboard dual two-frame elastic store slip buffers, and support for D4, ESF, and SLC-96 framing formats. It extracts and inserts robbed-bit signaling and includes programmable output clocks.

Telecom Procurement Notes

Verify the component status as discontinued. Confirm that the 'Q' suffix denotes the 44-pin PLCC package variant. Ensure compatibility with existing system designs regarding the specific package dimensions and pinout configuration before procurement.

Telecom Selection Notes

Select this component for applications requiring software-driven T1 framing with flexible orientation. Verify that the host microcontroller can interface with the multiplexed address/data bus. Ensure the design accommodates the 44-pin PLCC footprint and meets the specified voltage and temperature requirements.

Telecom Part Context

This part belongs to the DS2141A family of T1 controllers. The 'Q' suffix specifically identifies the 44-pin PLCC package version, distinct from the 40-pin DIP variant. It serves as a comprehensive framer designed to act as a slave or coprocessor to a microcontroller.
