DS34T104GN

Specialized ICS Overview

The DS34T104GN is a specialized integrated circuit designed for Time Division Multiplexing (TDM) applications, specifically functioning as a TDM-over-Packet (TDMoP) chip. Manufactured by Analog Devices Inc./Maxim Integrated, this device supports four ports and operates within a temperature range of -40°C to +85°C. It is housed in a 484-pin Thin Electronic Ball Grid Array (TEBGA) package measuring 23x23 mm. The component facilitates the transparent transport of E1, T1, E3, T3, or STS-1 streams over IP, MPLS, or Ethernet networks.

Specialized ICS Feature Summary

• Supports IETF PWE3 SAToP/CESoPSN/TDMoIP/HDLC compliant transport of up to eight E1/T1 streams or one high-speed E3/T3/STS-1 stream.
• Includes full-featured E1/T1 Line Interface Units (LIUs), framers, a TDMoP engine, and a 10/100 Ethernet MAC.
• Provides adaptive clock recovery and handles network packet delay variation (PDV), packet loss, and frequency changes.
• Supports multiprotocol encapsulation including IPv4, IPv6, UDP, RTP, L2TPv3, MPLS, and Metro Ethernet with VLAN support.

Specialized ICS Applications

• TDM Circuit Extension Over Packet Switched Networks (PSN)
• Cellular Backhaul Over PSN
• Multiservice Transport Over Unified PSN
• HDLC-Based Traffic Transport Over PSN

Specialized ICS Procurement Notes

Verify the specific ordering suffix when sourcing components. The 'GN' designation indicates a lead-free/RoHS-compliant package variant according to manufacturer documentation. Confirm the exact pin-package configuration matches the required 484 TEBGA form factor for board integration.

Specialized ICS Selection Notes

Select the DS34T104GN when four independent TDM ports are required for packet-based transport solutions. Ensure the design accommodates the 484-BGA footprint and provides appropriate thermal management for the operating temperature range. Verify compatibility with the required mapping methods such as SAToP, CESoPSN, or TDMoIP AAL1.

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 members share similar functional architectures but differ in port count and physical package types, such as TEBGA or HSBGA.

Specialized ICS Replacement Considerations

Compatible substitutes within the same family include the DS34T101GN, DS34T102GN, and DS34T108GN. Selection depends on the required number of TDM ports and the specific package type constraints of the target hardware design.
