::Hitesh:: 1,763 Report post Posted February 9, 2010 (edited) There's an insane number of parts, and the way they put it together seems, well, complex. Make sure you give the sliding mechanisms a peek near the bottom. For starters though, we introduce to you, the block diagram. The Qualcomm MSM7201A, which was previously used in later US iterations of the Touch Diamond and the Touch Pro (teardown coming!), comes full force in the G1. Similar to the BlackBerry Storm, the GPS and audio processing components are embedded into the processor. Fortunately, HTC has had much experience using the processor, although it runs a brand new OS. Running alongside the processor is the transceiver and power management ICs, Qualcomm RTR5285, and Qualcomm PM7540, respectively. For the actual PCBs, there are two main PCBs housing most of the components. The main PCB is shown directly below, while the "Chin" PCB that's literally housed in the chin section, is shown underneath. As shown above, Avago makes an appearance, providing amplifiers for both GSM and UMTS power amplifiers (ACPM-7381 & ACPM-7391), and TriQuint comes with its usual GSM power amplifiers (TQS 7M5008). The NAND Flash + DDR SDRAM is handled by a Samsung MCP. SMSC provides the USB PHY handling the connection from the processor to the PC. Asahi Kasei makes an interesting appearance with the first (to our knowledge) appearance of a compass IC. Texas Instruments takes care of the Bluetooth and Wi-Fi chips (both on the "Chin" PCB, shown above). The trackball, as noted by other teardowns, is the same module as the one on nearly every BlackBerry (except the upgraded trackball found on the Javelin). Another interesting thing is the two vibration motors included. One on the display module, and one on the main PCB. The display panels are shown below. This part is pretty cool, because housed within the screen casing is four large parts. On the front of the actual casing (image above, below left) is the capacitive touch panels, with Synaptics handling the controllers and everything else touchscreen-related. Finally, the moment you've all been waiting for. The back of the casing (shown below), showcases swooping action (we're seriously too in love). The translational springs on this puppy are strong as hell. But it needs to be so, since it has to drive a large screen around an arc. It's interesting to note how much effort HTC seems to have put in to produce a clean swooping action. Perhaps we're overthinking this. With everything set to go, here's your aggregated image!
