App note: Crystal oscillator troubleshooting guide

Sunday, April 28th, 2019

App note from NXP Semiconductors dealing with oscillators in microcontrollers. Link here (PDF) Most microcontrollers can use a crystal oscillator as their clock source. Other options include external canned oscillators, resonators, RC oscillators, and internal clocks. The main advantages of a crystal oscillator are frequency accuracy, stability, and low power...

Crystal oscillator teardown

Wednesday, April 17th, 2019

Here's a tear down of a crystal oscillator and a look at the silicon controller from Electronupdate:  Inside is a ceramic circuit board.  Ceramic has a low coefficient of thermal expansion which is probably very desirable here. It will also not absorb moisture.  All of this would affect the frequency. More details...

Crystal oscillator frequencies

Monday, January 7th, 2013

Drone refers us to this table of Crystal oscillator frequencies from Wikipedia: Wikipedia has a nice table of "Crystal oscillator frequencies". The table includes a column of crystals divisible by powers of 2 which may be appropriate for Real Time Clock (RTC) references... Xtal frequencies covered in the table (at...
