DS34T104GN+

Specialized ICS Overview

The DS34T104GN+ is a specialized integrated circuit designed for Time Division Multiplexing over Packet (TDMoP) applications. It supports four E1/T1/J1 ports and transports TDM or constant bit rate signals transparently over IP, MPLS, or Ethernet networks. The device integrates full-featured E1/T1 Line Interface Units (LIUs), framers, a TDMoP engine, and a 10/100 Ethernet MAC. It operates within an industrial temperature range of -40°C to +85°C and utilizes a 484-pin Thin-profile Ball Grid Array (TEBGA) package measuring 23x23 mm.

Specialized ICS Feature Summary

• Supports transport of up to four E1, T1, or serial streams over packet networks using SAToP, CESoPSN, TDMoIP AAL1, HDLC, and unstructured mapping methods.
• Integrates adaptive clock recovery machines per port with algorithms handling network PDV, packet loss, and frequency changes.
• Includes built-in E1/T1 LIUs and framers supporting G.703/G.704 standards and CAS signaling.
• Features a 10/100 Ethernet MAC with MII/RMII/SSMII support and selectable 32-bit, 16-bit, or SPI processor bus interfaces.

Specialized ICS Applications

• TDM Circuit Extension Over Packet Switched Networks (PSN)
• Cellular Backhaul Transport
• Leased-Line Services Over PSN
• HDLC-Based Traffic Transport

Specialized ICS Procurement Notes

Verify component authenticity through authorized distributors. Confirm RoHS compliance status as the '+' suffix indicates lead-free packaging. Check current availability as this specific part number may be subject to discontinuation notices from Analog Devices Inc./Maxim Integrated.

Specialized ICS Selection Notes

Select the DS34T104GN+ when four independent E1/T1 channels are required for TDMoP encapsulation. Ensure system design accommodates the 484-pin TEBGA footprint and provides necessary external SDRAM for buffer management. Verify that the host processor supports the required CPU interface modes.

Specialized ICS Part Context

This component belongs to the DS34T10x family, which includes single-port (DS34T101), dual-port (DS34T102), quad-port (DS34T104), and octal-port (DS34T108) variants. All share similar functional architectures but differ in port count and package types.

Specialized ICS Replacement Considerations

Public confirmed substitute part numbers: DS34T104GN (non-RoHS version). Other family members like DS34T102GN+ or DS34T108GN+ offer different port counts but share the same core technology.
