Overview / Main Features
The Motorola QIP7216 is a hybrid QAM/IP dual tuner HD DVR set top box designed for QAM/IPTV operators like Verizon FiOS. The QIP7216 comes with conditional access module (M-Card), a 160GB hard disk drive for DVR storage and features multi-room broadcast using MoCA technology. High Definition (HD) outputs via IEEE1394, Component and HDMI while standard definition (SD) outputs via composite, S-Video and RF. Input ports include eSATA, USB and, of course, Ethernet.

Release and Availability
Per our understanding, early 2010
Pricing for this kind of product (at the consumer level) is typically meaningless as it is a completely subsidized part of a service package. Cable set-top boxes are typically rented out to subscribers on a monthly schedule in accordance with the service contract which varies region to region within the North American market. Since the device cannot function without being properly set-up by a service provider, after-market product and prices have no validity.
For the purposes of this teardown analysis, we have assumed a lifetime production volume of 1M units.
As a reminder, teardown volume production assumptions are primarily 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). Unless assumed, volumes increment by an order of magnitude. Minor changes in volume (say 1 million vs. 2) rarely have a large net effect on our final analysis.

What Is Not Included in our Cost Analysis
The total materials and manufacturing costs reported in this analysis reflect ONLY the direct materials cost (from component vendors and assorted EMS providers), AND manufacturing with basic test. Not included in this analysis are costs above and beyond the material manufacture of the core device itself - cost of intellectual property, royalties and licensing fees (those not already included into the per component price), software, software loading and test, 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 and exceptionally in some circumstances the packaging and literature as well.
Country of Origin / Volume Assumptions
Based on markings, the unit was assembled in China. Furthermore, we have assumed that custom mechanicals (plastics, metals, etc.) were also sourced in within mainland China.
Country of origin assumptions relate directly to the associated cost of manufacturing, where calculated by iSuppli. In the cases of 'finished' sub-assemblies (such as hard drive), we do not calculate internal manufacturing costs, but rather assess the market price of the finished product in which case country of origin assumptions may or may not have a direct effect on pricing.
Remember also that labor rates are applied directly only to hand inserted components and systems in our bill of materials, and although regional assumptions do, these new rates do not have a direct effect on our modeled calculations of placement costs for automated SMD assembly lines. "Auto inserted components (such as SMT components) placement costs are calculated by an iSuppli algorithm which allocates a cost per component based on the size and pin-count of the device. This calculation is affected by country or region of origin as well.
Design for Manufacturing / Device Complexity
The QIP7216 has an overall component count of 1883 (excluding box contents), of which 1346 of that total component count is from the Main PCB.
Component counts have a direct bearing on the overall manufacturing cycle times and costs, and also can increase or decrease overall yields and re-work. Our calculations of manufacturing costs factor counts and more qualitative complexities in the design. The cost of manufacturing is also, to some extent, decreased in this case because of assumed labor rate applied for China.
Note that manual labor has a much smaller effect on auto-insertion assembly lines (for the Main PCB, for example), where manufacturing costs are much more capital equipment intensive and driven by these investment costs.
Like most other conventional QAM set top boxes on the market, the hybrid Motorola set top is also primarily a Broadcom design. At the Front End of the QIP7216 , we find the Broadcom BCM3250 single chip QAMLink IC. The back end video decoding is handled by a BCM7400 HD Video System on Chip. Entropic Communications provides a chipset for MoCA-based networking featuring both the EN2210-BG2 controller and EN1010C1 front end interface. TI maintains the IEEE1394 microcontroller slot for this legacy output port and a combination of Hynix, Spansion and Winbond provides the memory solutions.
A 160GB hard disk drive by Seagate is used for DVR storage.
