Section 2.2.2 of pic18f4550 datasheet says:
In HS, HSPLL, XT and XTPLL Oscillator modes, a crystal or ceramic resonator is connected to the OSC1 and OSC2 pins to establish oscillation. Figure 2-2 shows the pin connections. The oscillator design requires the use of a parallel cut crystal.
Note: Use of a series cut crystal may give a frequency out of the crystal manufacturer’s specifications.
How do I know the type of a crystal? Which type is more widespread?
I'm planning to buy a crystal from here http://belchip.by/section/?selected_section=02156&filter_var=&page=1&limit=120&query=&sorting=price
How do I select the right one, there is no any data about them. Maybe it's possible to tell the type by their look?
Also why, when and how does the type matter?
