DS26524G+

Telecom Overview

The DS26524G+ is a single-chip quad T1, E1, and J1 framer and line interface unit (LIU) combination. It integrates four independent transceivers capable of supporting both long-haul and short-haul lines. The device operates within a temperature range of 0°C to +70°C and utilizes a 256-ball TE-CSBGA package. Each channel allows for independent protocol selection, accommodating twisted pair or coaxial applications through internal software-selectable termination.

Telecom Feature Summary

• Integrates four complete T1, E1, or J1 transceivers combining LIU and framer functions on a single chip.
• Supports crystal-less jitter attenuation in transmit or receive paths to meet international telecommunications standards.
• Provides flexible signaling extraction and insertion via system interface or microprocessor port.
• Includes comprehensive alarm detection, insertion capabilities, and multiple framing format support.

Telecom Applications

• Routers
• Channel Service Units (CSUs)
• Data Service Units (DSUs)
• Multiplexers (Muxes)
• T1/E1 Test Equipment

Telecom Procurement Notes

Verify the specific ordering suffix against current manufacturer documentation before procurement. Confirm that the component meets RoHS compliance requirements if applicable to the target assembly process. Ensure the selected package variant matches the intended PCB footprint design constraints.

Telecom Selection Notes

Select this component when a compact solution for multi-port telecom interfacing is required. Evaluate the thermal characteristics of the TE-CSBGA package against the operating environment. Verify that the host processor interface supports the necessary control protocols for configuration and monitoring.

Telecom Part Context

This part belongs to the DS26524 family of quad transceivers manufactured by Analog Devices / Maxim Integrated. The 'G+' designation indicates a lead-free and RoHS-compliant version of the standard DS26524G device. It serves as a core interface element in digital telecommunication infrastructure.

Telecom Replacement Considerations

The DS26524GN+ offers an extended industrial temperature range (-40°C to +85°C). The DS26524GA5 is another variant within the same product family. Verify pin compatibility and electrical specifications before substituting these parts.
