DS34S108GN

Specialized ICS Overview

The DS34S108GN is a single-chip TDM-over-Packet (TDMoP) device from Analog Devices/Maxim Integrated, designed for transparent transport of up to eight E1, T1, or serial streams over IP, MPLS, or Ethernet networks. It supports IETF PWE3 SAToP/CESoPSN/TDMoIP/HDLC standards and handles jitter/wander conforming to G.823/G.824 and G.8261 specifications. The component operates on a low-power 1.8V core with 3.3V I/O, housed in a 484-pin HSBGA package (23x23mm). It features an integrated 10/100 Ethernet MAC, adaptive clock recovery, and up to 64 independently configurable bundles.

Specialized ICS Feature Summary

• Includes an on-chip 10/100 Ethernet MAC supporting MII/RMII/SSMII interfaces.
• Provides adaptive clock recovery capable of handling network PDV, packet loss, and frequency changes.
• Features glueless SDRAM buffer management and selectable 32-bit, 16-bit, or SPI processor buses.

Specialized ICS Applications

• TDM Circuit Extension Over PSN
• Cellular Backhaul Over PSN
• Multiservice Over Unified PSN

Specialized ICS Procurement Notes

Verify the lead-free status indicated by the '+' suffix if required, as the base model may differ. Confirm the specific revision against known errata via manufacturer documentation before finalizing procurement plans.

Specialized ICS Selection Notes

Select this model when eight independent TDM ports are required within a single package. Ensure the design accommodates the 484-pin HSBGA footprint and provides external SDRAM for buffer management.

Specialized ICS Part Context

This part belongs to the DS34S10x family, which includes variants with one, two, and four ports (DS34S101, DS34S102, DS34S104). All share identical functional architectures but differ in port count and pin-package configurations.

Specialized ICS Replacement Considerations

The DS34S108GN+ is the lead-free/RoHS-compliant version of this component. Verify pin compatibility and electrical characteristics before substitution.
