First Run of Raspberry Pi Boards To Be Completed Feb 20th 181

Posted by Unknown Lamer from the hurry-up-and-take-the-money dept.
An anonymous reader writes "Raspberry Pi has confirmed the first batch of $35 PCs will be constructed on February 20. They've also coaxed Broadcom into releasing the datasheet for the board. Apparently the company hit a snag with the quartz crystal package so there was a manufacturing delay, but it's since been resolved and things are on schedule for later this month." From the announcements: "Eben and I may be going to China to make sure that the boards can be brought up properly for that date if necessary. We’ll be airfreighting them to the UK immediately, so you should be able to buy them before the end of the month."

      This is a very competitive space, and Broadcom does not want a competitor to find a weakness in their product or duplicate a feature that other SOCs do not currently have (which may have been the reason this chip was used for the rasberry pi in the first place).

      That said, I find it somewhat disappointing that an open source project is dependent on a chip that is not able to/does not release complete specifications. But at least (apparently) the important parts of the datasheet were released.

      They're available in a myriad of sizes and configurations and while there's some basic standards, there are variations among mfrs, not so much in the pad layout, but in things like how far the weld on the can sticks out, and so forth.

      Quoting user shirro from the Raspberry Pi comments [raspberrypi.org]:

      Quartz crystals provide a clock signal that regulates all the other components. They utilize the mechanical resonance of the crystal to produce a stable electrical oscillator. http://en.wikipedia.org/wiki/Crystal_oscillator [wikipedia.org]

      Digital circuits such as microprocessors have delays in processing and moving data about and a clock is required to regulate the system so that data is not read before it is available. Different parts move at different speeds and the master clock is divided down to appropriate rates for each component of the system.

      Quartz crystals for geeks 101:

      Quartz crystals are the basis of reliable, relatively frequency stable oscillators. They are at the heart of most every computer system of any size or complexity (yes, some use RC oscillators, others use more exotic stuff, but, we're talking the 99% here...)

      Without a reliable time source, you cannot do asynchronous serial communications and any number of other things that require your computer to have the same sense of time as another computer it is attempting to talk to.

      These same crystals are also at the frequency basis for many radio systems for similar reasons, except in the radio realm the crystals can be used to control the radio frequency for transmitters and receivers to lock to each other without much tuning fuss.

      Extra geek points if you remember the crystal color combinations to make Sleestak repellent noise (from Land of the Lost).

    • Any time you see a CPU speed listed for a computer, you're actually seeing information about a quartz crystal. For example, the Raspberry Pi has a 700 MHz processor, which really means that there's a stable clock source timed to oscillate 700 million times per second. At the core of this clock source is a quartz crystal to serve as a time reference.

      It's rare to see the oscillation frequency of a crystal to be used directly as a clock frequency nowadays, so don't assume that the crystal in the RP is 700 MH
