How to Choose the Frequency of Epson Crystal Vibration

Release date:2018-10-15 Author:Guan Shuo Click:

In Epson crystal oscillator, both active and passive crystal oscillators have abundant standard frequency values to choose from, and EPSON also provides customized production of special frequency points.

Different from the nominal capacitance and resistance values of patch capacitors and patch resistors, there is no such standard capacitance or resistance value as E-24E-96 for frequency components as crystal oscillators and resonators. So what frequency value is more appropriate for new product development?

I. Industrial Automation, Intelligence and Industrial Control

1. The main frequencies of bank financial system/encrypted dog/tax control system/remote meter reading system/test instrument/ultrasonic wave are 50.000MHz, 3.579545MHz, 48.000MHz and 4.000MHz.

12.000MHz, 50.000MHz, 10.000MHz, 8.000MHz, 6.000MHz.
