DS2154LA2+

Drivers, Receivers, Transceivers Overview

The DS2154LA2+ is an enhanced E1 single-chip transceiver manufactured by Analog Devices Inc./Maxim Integrated. It provides complete E1 (CEPT) PCM-30/ISDN-PRI transceiver functionality within a 100-pin, 14mm x 14mm LQFP package. The device operates at a supply voltage of 4.75V to 5.25V and supports a commercial temperature range of 0°C to +70°C. It integrates on-board clock/data recovery, waveshaping for 120Ω and 75Ω lines, and a crystal-less jitter attenuator with selectable 32-bit or 128-bit depth.

Drivers, Receivers, Transceivers Feature Summary

• Integrates complete E1 transceiver functions including framing, signaling extraction, and alarm detection.
• Features on-board long- and short-haul line interface with adjustable build-outs for twisted-pair and coaxial cables.
• Includes dual elastic store slip buffers to accommodate asynchronous backplane connections up to 8.192MHz.
• Provides an 8-bit parallel control port compatible with Intel or Motorola bus architectures.

Drivers, Receivers, Transceivers Applications

• E1 Line Interface Units (LIUs)
• PCM-30 systems
• ISDN-PRI interfaces

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'A2' against official documentation, as standard listings typically show 'L', 'LN', or 'LD2'. Confirm RoHS compliance status and lead-free packaging details directly with the manufacturer or authorized distributors, as ordering suffixes may indicate specific material or revision changes not universally documented in general catalogs.

Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring full E1 protocol support with integrated jitter attenuation and elastic stores. Ensure the design accommodates the 100-LQFP footprint and 5V power requirements. Verify that the required temperature range aligns with the commercial grade specifications provided for this variant.

Drivers, Receivers, Transceivers Part Context

This device belongs to the DS2154 family of enhanced E1 single-chip transceivers from Maxim Integrated (now Analog Devices). It serves as an evolution of the DS2153, offering expanded features such as nonmultiplexed bus operation, per-channel loopback, and improved receive sensitivity. The family is designed for telecom infrastructure requiring robust E1 line interfacing.

Drivers, Receivers, Transceivers Replacement Considerations

Direct pin-compatible alternatives include the DS2154L+, DS2154LN, and DS2154LN+. For T1 applications, the DS2152 is noted as pin-compatible. Verify functional equivalence regarding specific feature sets like elastic store capabilities and bus interface modes before substitution.
