DS34T102GN+

Specialized ICS Overview

The DS34T102GN+ is a dual-port TDM-over-Packet (TDMoP) integrated circuit designed for transparent transport of E1, T1, or serial streams over IP, MPLS, and Ethernet networks. It operates on a 3.3V supply with a -40°C to +85°C industrial temperature range. The device integrates full-featured E1/T1 Line Interface Units (LIUs), framers, a TDMoP engine, and a 10/100 Ethernet MAC within a 484-pin TEBGA package. It supports up to 64 independently configurable bundles and handles adaptive clock recovery to maintain signal integrity across packet-switched networks.

Specialized ICS Feature Summary

• Dual-channel architecture supporting simultaneous E1/T1 stream encapsulation
• Comprehensive mapping support including SAToP, CESoPSN, TDMoIP AAL1, HDLC, and Unstructured formats
• On-chip jitter buffer control and clock recovery machines for each port
• Integrated 10/100 Ethernet MAC with MII/RMII/SSMII interface options

Specialized ICS Applications

• TDM Circuit Extension Over Packet Switched Networks (PSN)
• Cellular backhaul connectivity via PSN infrastructure
• Leased-line services delivery over GPON/EPON or cable networks
• HDLC-based traffic transport in multiservice environments

Specialized ICS Procurement Notes

Verify component authenticity through authorized Analog Devices or Maxim Integrated distribution channels. Confirm RoHS compliance status and check for specific manufacturing lot dates against current lifecycle notices. Ensure the ordering suffix matches the required lead-free specification for environmental compliance.

Specialized ICS Selection Notes

Select this model when two independent TDM ports are required for network edge aggregation. Compare against the DS34T101GN+ for single-port needs or the DS34T104GN+ for quad-port density. Verify that the 484-pin TEBGA footprint aligns with existing PCB layout constraints and thermal management capabilities.

Specialized ICS Part Context

This component belongs to the DS34T10x family of TDM-over-Packet chips, which also includes the DS34T101, DS34T104, and DS34T108 variants. These devices share a common architectural foundation for transporting TDM signals over packet networks but differ in the number of supported physical interfaces and bundle capacities.

Specialized ICS Replacement Considerations

Direct pin-compatible replacements within the same series include the DS34T101GN+ (single port) or DS34T104GN+ (quad port), provided port count adjustments are acceptable in the design. Cross-series migration requires verification of register compatibility and timing characteristics.
