Very Good Stability +/- 500 PPB Abracon 2520 case TCXO / VCTCXO

grabcad

This is a model of a Abracon Voltage Controlled, Temperature Compensated, Crystal Oscillator (VCTCXO) that has a frequency stability of +/- 500 Parts Per Billion (PPB). This is the Abracon ASTX-12 series of parts with a '2520' case size (2.5 x 2.0 mm).The accuracy of this oscillator is such that there are 2x more stable than a 1 Parts Per Million (PPM). To give context, a standard crystal is typically about +/- 50 PPM, so this crystal is 50 * 2 = 100 times more stable.This is important for frequency responses that cannot tolerate inaccuracy for clocks and frequency control. It also means that for a Radio Frequency (RF) circuit better stability as well as accuracy.For low power RF circuits, this means that there is less wake up time for protocol resynchronization.The standard frequency is 10 MHz and ranges up to 52 MHz.Here's some basic information ;https://www.mouser.com/new/abracon/abracon-astx-txco/For more information go to Abracon's website :https://abracon.com/parametric/oscillators/?page=1&part_type=VCTCXO&part_status=Active&limit=100&length_mm=2.5
