DS2154LNA2+

Drivers, Receivers, Transceivers Overview

The DS2154LNA2+ is a single-chip transceiver (SCT) designed for E1 line connectivity. It integrates clock/data recovery, jitter attenuation, framing, and HDLC control to convert AMI/HDB3 waveforms to NRZ streams. The device supports 75Ω coaxial and 120Ω twisted-pair interfaces with adjustable line build-out. It features a 100-pin LQFP package and operates within a temperature range of -40°C to +85°C.

Drivers, Receivers, Transceivers Feature Summary

• Complete E1 PCM-30/ISDN-PRI transceiver functionality
• On-board long- and short-haul line interface for clock/data recovery
• Configurable 32-bit or 128-bit crystal-less jitter attenuator
• Integral HDLC controller with 64-byte buffers

Drivers, Receivers, Transceivers Applications

• E1 line interface units
• Telecommunications network equipment
• Digital cross-connect systems

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'LNA2+' against official manufacturer documentation to confirm pinout, voltage supply requirements, and revision status. Ensure compatibility with existing system designs before procurement.

Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring full E1 compliance with integrated signal conditioning. Consider the 100-pin LQFP footprint and operating temperature range when designing the PCB layout and thermal management strategy.

Drivers, Receivers, Transceivers Part Context

This device is part of the DS21354/DS21554 family, serving as an upward-compatible version of earlier SCTs like the DS2154. It retains original software compatibility while adding features such as an HDLC controller and interleaving bus operation.

Drivers, Receivers, Transceivers Replacement Considerations

The DS21354LN+ is a pin-compatible alternative within the same family. Verify voltage supply differences (3.3V vs 5V) and feature set alignment before substitution.
