DS2180AQ+

Telecom Overview

The DS2180AQ+ is a monolithic CMOS T1 transceiver designed for primary rate (1.544 MHz) transmission systems. It supports 193S and 193E framing standards with selectable zero suppression modes including B7 stuffing, B8ZS, and transparent operation. The device features a serial interface for configuration in processor mode or hardware control without a host processor. It operates on a single 5V supply within an industrial temperature range of -40°C to +85°C. The component is housed in a 40-pin PLCC surface-mount package.

Telecom Feature Summary

• Supports common T1 framing standards including 193S and 193E formats
• Provides selectable zero suppression modes such as B7 stuffing, B8ZS, and transparent data handling
• Enables mixed clear and non-clear DS0 channels on the same link via robbed bit signaling
• Includes integrated alarm generation, detection, and receive error counting capabilities

Telecom Applications

• Primary rate T-carrier transmission systems
• Ft/Fs applications requiring 193S framing support
• Extended superframe format implementations
• Clear channel capability environments

Telecom Procurement Notes

Verify the specific suffix 'Q' indicates the industrial temperature grade (-40°C to +85°C) and PLCC package type. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure pin compatibility with existing 40-pin DIP footprints if transitioning from legacy designs.

Telecom Selection Notes

Select this component for standalone T1 transceiver applications requiring robust alarm monitoring and flexible framing options. Consider the hardware mode feature for designs that cannot accommodate a host processor. Verify power supply requirements align with the specified 5V operation and check thermal constraints for the PLCC package.

Telecom Part Context

This device belongs to the DS2180A family of T1 transceivers. It is compatible with other components in the series such as the DS2186 transmit line interface, DS2187 receive line interface, and DS2188 jitter attenuator. The 'AQ' designation specifically denotes the industrial temperature range and surface-mount packaging variant.

Telecom Replacement Considerations

Direct replacements include the DS2180AN for DIP packaging or the standard DS2180A for commercial temperature ranges. Verify register compatibility when substituting with other members of the DS2180 family to ensure functional parity.
