In the quest for an accurate frequency standard there are many options depending on your budget, but one of the most affordable is an oven controlled crystal oscillator (OCXO). [RF Burns] has a ...

Enter the oven controlled crystal oscillator, or OCXO. These do basically what it says on the tin, but what’s inside them? [Kerry Wong] took apart a vintage Toyocom TCO-627VC 10 MHz OCXO ...

Microchip has combined a chip-scale caesium atomic clock for good accuracy with a ovened crystal oscillator for good phase noise, in a through-hole ...

The power supply is typically 3.3V, but it can be as low as 1.8V while the RTC still functions properly. The oscillator works in parallel resonant mode of the crystal. When a 32768Hz quartz crystal is ...
