Solution: Frequency accuracy (sometimes called timing accuracy) is usually given in parts per million (ppm) of the sample rate. This value depends on the device that you are using and can be found in the device's specifications. In ppm calculator chemistry addition to frequency accuracy (fa), frequency error (fe) is also something that you can calculate, using the equations below:Measured frequency (fm) = signal frequency (fs) ± frequency error (fe). Rearranging the above equation to solve for frequency error: Frequency error (fe) = signal frequency (fs) * frequency accuracy (fa). Examples:Consider a case in which you are measuring a precise 100kHz sine wave, using a device with a frequency accuracy of 25 ppm. The frequency error will be 100,000Hz * 25/1,000,000 = 2.5Hz. Therefore, the frequency accuracy is 100kHz ± 2.5Hz.Consider a case in which you are generating a 1kHz sine wave, using a device with a frequency accuracy of 50 ppm. The frequency error will be 1,000Hz * 50/1,000,000 = 50mHz. Therefore, the frequency accuracy is 1kHz ± 50mHz. Related Links: KnowledgeBase 1F5DD5KD: What Is Meant by the Stabi

I am trying to design http://electronics.stackexchange.com/questions/15851/what-is-the-ppm-in-the-crystal-oscillator a PCB using the TI CC2540 sample design. There is a MC-306 (32.768kHz, 12.5pf, and 20/50ppm). I don't know what the 20/50ppm rating is. For me, the size is very important, so I decided to replace it with the FX135A, but its ppm is -20/+20. Will it cause a problem if I use this one instead? What is the ppm rating in the crystal oscillator? oscillator share|improve this question edited Aug 9 '14 at 13:37 Ricardo 3,893102856 asked Jun 23 '11 at 13:16 OHLÁLÁ 4432716 add a comment| 2 Answers 2 active oldest votes up vote 24 down vote accepted Like Olin said, ppm stands for parts per million, and it indicates how much your crystal's frequency may deviate from the nominal value. The MC-306 exists in a 20 ppm and a 50 ppm version. For the 20 ppm version this means that the frequency will be between 32.7673 kHz (32.768 - 20 ppm, or x 0.999980) and 32.7687 kHz (32.768 + 20 ppm, or x 1.000020). These numbers may give you a comfortable feeling, but remembe

Run WinDaq and Begin Recording on Windows Startup » What's All This PPM Stuff? Data Logger > Products More times than not when talking to a customer about clock accuracy and I mention a spec in units of parts per million (PPM) the response is, "Huh? What's PPM?" Fair enough, but first some background: Behind every great clock there's a crystal, a piezoelectric device that vibrates at a precise and known frequency. There are other ways to generate frequencies (a resistor and capacitor combination is one of them), but none are more accurate. Many of our data logger products provide a built-in date and time clock that the instrument uses to time and date stamp recorded data. If you record temperature and humidity, for example, you'll be able to determine the date and time of occurrence to a precision that is determined by the accuracy of crystal that drives the date-and-time chip that's embedded in the instrument. For reasons known only to crystal manufacturers, crystal accuracy is speced in units of PPM. Lower PPM crystals cost more than higher PPM, and manufacturers like us who use crystals in our products make a price/performance judgement call and then simply spec time-and-date clock accuracy at whatever PPM number is associated with the choice. So how do you use PPM to put the figure into the context of your application? I'll answer that with an example. The de facto standard in the industry for crystal inaccuracy is 20 PPM, which is always interpreted as a plus or minus number (±20 PPM). In a general sense, for this inaccuracy fig
