Netgear DG834GT SuperWireless 108Mbps ADSL Router Teardown

30 November 2012
The following is an overview of a teardown analysis conducted by IHS Technology Teardown Services.

Main Features / Overview

802.11b/g wireless ADSL router with 4 physical ports and newer 108Mbps data speed. No particular proprietary spin or extra technology of note.

Target Market

Home and small office networking users.

Release

"Unveiled in November 2004" per June, 2005 Netgear press release.

Pricing / Availability

Pricing seems to range from about $120 to $180 depending on the source. Although similar models are available in the US, this particular model is not available in North America. Seems to be, from links found, UK-oriented.

Volume Estimations

For the purposes of this cost analysis we have assumed a total production volume over product lifetime of 1M units of this particular model. As a reminder, volume production assumptions are not meant to be necessarily "market accurate", and our meant primarily to be used for our cost analysis in terms of amortized NRE and tooling costs, especially for custom components specific to the model being analyzed (mechanical components especially).

Function / Performance

No functional testing was performed on this device.

Cost Notes

Main Cost Drivers within Router Itself (representing approximately 63% of total materials costs)

Atheros AR5005GS Wireless card $11

Broadcom - BCM6348KPB - ADSL2+ CPE Device~$10

Broadcom - BCM5325EKQM Ethernet Switch - 5-Port ~$4

Hynix - HY57V283220(L)T(P)-7 - SDRAM - 128Mbit ~$3

Macronix - MX29LV320ABTC-90 - Flash - 32Mb~$2

Subtotal Main Cost Drivers ~$30

Total Materials Costs ~$48

Materials and Manufacturing* ~$52



* - The total materials and manufacturing costs reported in this analysis reflect only the direct materials cost (from component vendors and assorted EMS providers), manufacturing and test. Not included in this analysis are costs above and beyond the manufacture of the core device itself - cost of shipping, logistics marketing and other channel costs including not only EMS provider and the OEM's margin, but that of other resellers. Our cost analysis is meant to focus on those costs incurred in the manufacture of the core device itself.

Manufacturing Notes<

Country of Origin / EMS Provider

This device was labeled made in Taiwan, which is becoming more and more and rare in favor of mainland China. We nonetheless are assuming that plastics, mechanicals and PCBA assembly took place in the PRC.

Design for Manufacturing / Device Complexity

This device is fairly modular, straightforward and has a minimal number of components. At a high level it consists of the main PCB, a modular 802.11b/g wireless Mini-PCI card solution from Atheros, and a limited number of mechanical / enclosure components. The Main PCB has few components, as it is fairly integrated relying on two Broadcom chips to provide the majority of circuit functionality, and the Atheros card really has only one significant Atheros chip. As a result, manufacturing is straightforward and involves relatively low human intervention / hand assembly. The device has an overall component count of only 345 components.

Design Notes

The main PCB has really only 2 major, noteworthy ICs of which two are part of a Broadcom chipset solution - the BCM5325EKQM, Ethernet Switch - 5-Port, 10/100, BCM6348KPB, ADSL2+ CPE Device - Single-Chip, Integrated CPU, Transceiver and AFE. The wireless function is entirely self-contained on a mini-PCI card produced per an Atheros reference design - AR5005GS - 108Mbps, 802.11b/g. The whole xcard essentially revolves around 1 chip - the AR2414 Single-Chip CMOS MAC/Baseband/Radio.
