Aker Technology USA Corporation
Crystal Oscillators - the 'heartbeat' for an MCU not require the internal oscillator of the digital signal processor (DSP.) It has good signal quality and stability, and does not require a complicated configuration, so it is relatively simple to connect. It uses a PI filter network comprised of a capacitor and an inductor as well as a small-value resistor at the output to filter the signal. The quartz crystal oscillator has a fixed signal level, so an appropriate output level needs to be selected. For applications with sensitive timing requirements...
