You can usually tell a Colpitts oscillator by remembering it starts with C and the feedback loop has a split capacitor (as opposed to a tapped inductor). The post also looks at Pierce oscillator ...

We’ve read a lot about oscillators, but crystal oscillators seem to be a bit of a mystery. Hobby-level books tend to say, build a circuit like this and then mess with it until it oscillates.

This IP is a crystal oscillator DUP IO pad designed for low-power consumption applications. The pierce oscillator works in parallel mode and supports a frequency ranged from 2MHz to 8MHz, with the ...

Optimized for Semiconductor Manufacturing International Corporation (SMIC) 0.13μm Logic Salicide 1.2/3.3V process, S13V25_OSCIO_02 provides a crystal oscillator IO pad designed for low-power ...
