DS26522GN

Drivers, Receivers, Transceivers Overview

The DS26522GN is a dual-channel framer and line interface unit (LIU) combination designed for T1, E1, and J1 applications. It integrates complete transceiver functionality within a single package. The device supports both long-haul and short-haul lines with independently configurable channels. It operates within an extended temperature range of -40°C to +85°C. The component utilizes a 144-pin CSBGA package for surface-mount installation.

Drivers, Receivers, Transceivers Feature Summary

• Supports internal software-selectable termination for twisted pair and coaxial applications
• Includes crystal-less jitter attenuator compliant with ETS CTR 12/13 and ITU-T standards
• Provides flexible signaling extraction and insertion via system interface or microprocessor port

Drivers, Receivers, Transceivers Applications

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

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix 'GN' against current manufacturer documentation to confirm the -40°C to +85°C operating temperature range and 144-pin CSBGA package configuration. Confirm lead-free status if required by project specifications. Ensure compatibility with existing board layouts due to the specific pinout requirements of this package type.

Drivers, Receivers, Transceivers Selection Notes

Select this component when a combined framer and LIU solution is required for T1, E1, or J1 networks. Consider the integrated jitter attenuation capabilities and flexible signaling options. Verify that the host system can support the necessary parallel or serial peripheral interface (SPI) control mechanisms for configuration and monitoring.

Drivers, Receivers, Transceivers Part Context

This part belongs to the DS26522 family of dual T1/E1/J1 transceivers manufactured by Analog Devices Inc./Maxim Integrated. The 'GN' suffix specifically denotes the industrial temperature grade (-40°C to +85°C). Other variants in the series include the 'G' suffix for commercial temperature grades. The device serves as a critical interface between digital cross-connect systems and telecom transmission lines.
