Telecom datasheet and documents for DS2155LN+

DS2155LN+

Telecom Overview

The DS2155LN+ is a software-selectable T1, E1, or J1 single-chip transceiver designed for short-haul and long-haul applications. It integrates a line interface unit (LIU), framer, HDLC controllers, and a TDM backplane interface controlled by an 8-bit parallel port supporting Intel or Motorola bus operations. The device operates within a temperature range of -40°C to +85°C and utilizes a 100-pin LQFP package.

Telecom Feature Summary

Complete T1/DS1/ISDN-PRI/J1 and E1 PCM-30/ISDN-PRI transceiver functionality
Long-haul and short-haul line interface with crystal-less jitter attenuator
Dual HDLC controllers and programmable BERT generator/detector
Internal software-selectable termination resistors for 75Ω, 100Ω, and 120Ω interfaces

Telecom Applications

T1/E1/J1 Line Cards
Switches and Routers
Add-Drop Multiplexers

Telecom Procurement Notes

Verify the specific suffix 'LN+' against official documentation to confirm lead-free compliance and extended industrial temperature rating (-40°C to +85°C). Ensure compatibility with existing board layouts requiring a 100-pin LQFP footprint. Cross-reference current availability status directly with Analog Devices or authorized distributors as product lifecycles may change.

Telecom Selection Notes

Select this component when a unified solution for T1, E1, and J1 protocols is required on a single chip. The software-selectable nature allows flexibility in network configuration without hardware changes. Consider the integrated jitter attenuator and elastic store buffers if asynchronous backplane connections up to 16.384MHz are needed.

Telecom Part Context

The DS2155LN+ belongs to the Maxim Integrated DS2155 family of telecom interface ICs. It is pin and software compatible with the DS2156. The 'L' indicates the LQFP package type, while 'N' denotes the extended industrial temperature range. The '+' suffix signifies a lead-free/RoHS-compliant manufacturing process.
