a belated thx. from your photos it appears that the 4 Hynix DDR 3L chips are on both the front and back of the motherboard - 2 a side. Unlike PoP config they are not on the SoC but offset from them as in the iPad3. Like the A5x the Tegra 3 too seems to require a Heat Sink - the consequences of cramming too many Graphics cores with a 45 nm, non HKMG process perhaps ?

It is a very good piece of hardware, since Google is not revenue centric from hardware, it would be better if they had kept this an open source hardware so that it can be better replicated thought the world.

I believe Nexus 7 comes with a camera. Do you know who supplies the camera module?

It seems that Google has a good entry with the Nexus 7 tablet. I would like to take one for a test drive to see how fast it is and what the battery life is like under normal usage.

Apple always use dialog PMU SoC for iphone or ipad. I don't know why they change the PMU vendor. It's not good idea for doing this.

Good question for this article. Battery management is big challenge for smartphone or tablet. My Samsung Galaxy-R can only last for about 5-6 hours if I listening musics,watching moives and using google maps for navigation.

Is Maxim already dominating the PMU in tablet market? It seems Apple also use Maxim PMU in the iPAD.

is that $184 BOM estimate based on a 1000 pcs or more BTW ? its still very good for a £159 for 8GB and £199 for the 16GB version in the UK price, released in retail just as the 2012 Olympics start there. not to forget there's all that new free Virgin media cable/ wireless underground connectivity now put in place ready for the massive games visitors there too so no problem getting any web content and streaming etc you please with it. even if the UK goggle shop content isn't great right now as the content providers don't seem to want to take your 2012 Olympics games money and actually pay for their online content there. oh well the end users will be happy anyway a quad core and you can provide your own content, cant stop the net.

putting a LPDDR2 PoP version on there rather than the better DDR3 would have slowed down the data throughput would it not, so im glad they went DDR3 its still a single channel right ? and so not perfect for gaining extra free speed, at least until the real Wide IO ram makes an appearance.

Can the battery last long ?

LATEST ARCHIVED BROADCAST
As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
