DS3150TN+

Telecom Overview

The DS3150TN+ is a Line Interface Unit (LIU) manufactured by Analog Devices Inc./Maxim Integrated, designed for physical layer interfacing to DS3, E3, and STS-1 lines. It operates within an industrial temperature range of -40°C to +85°C and utilizes a 48-pin TQFP package. The device supports a supply voltage of 3.3V with I/O tolerance up to 5V. Key electrical parameters include a maximum operating current of 110mA and a data rate capability of 51.840 Mb/s. It features a single channel configuration and interfaces directly to 75 Ω coaxial cable.

Telecom Feature Summary

• Integrated transmitter, receiver, and jitter attenuator for DS3, E3, and STS-1 line interfacing
• Built-in B3ZS and HDB3 encoder/decoder supporting both bipolar and NRZ interfaces
• Adaptive equalizer block compensating for cable losses from 0dB to 15dB
• On-board PRBS generator and detector for physical layer testing

Telecom Applications

• SONET/SDH and PDH Multiplexers
• Digital Cross-Connects
• Access Concentrators
• ATM and Frame Relay Equipment
• Routers

Telecom Procurement Notes

Verify the specific suffix 'TN+' against official datasheets to confirm the 48-TQFP package and industrial temperature rating (-40°C to +85°C). Confirm RoHS compliance status as indicated in manufacturer documentation. Check for obsolete status or discontinuance notices prior to procurement planning.

Telecom Selection Notes

Select the DS3150TN+ when a 48-pin surface-mount package is required for industrial temperature applications. Ensure the design accommodates 3.3V logic levels with 5V tolerant I/O. Verify that the application requires support for DS3, E3, or STS-1 standards over 75 Ω coaxial cabling.

Telecom Part Context

The DS3150 series includes variants such as the DS3150QN (28-pin PLCC) and commercial temperature versions like the DS3150T. The DS3150TN+ specifically denotes the industrial temperature grade variant housed in a 48-pin TQFP package, distinguishing it from lower-temperature or different package options within the same functional family.

Telecom Replacement Considerations

The device is documented as a drop-in replacement for TDK 78P2241/B and 78P7200L. It is also pin-compatible with the TDK 78P7200. Verify pinout compatibility before substituting these legacy components.
