3 Pin Ceramic Resonator Pinout

Hi i just got in 4 10mhz ceramic resonators and i have no idea how to put them in my circuit.

3 pin ceramic resonator pinout. Just keep in mind the datasheet note about ceramic resonators. The 3 pin resonators have the capacitors fitted internally. 4 000 mhz resonant resistance. I m going to go out on a limb here and guess that the two outside pins go to the to osc1 and osc2 on the chip that will be using it it s a qprox qt150 btw and then maybe the middle pin gets grounded.

3 pin ceramic resonator for use with microcontroller circuits. When connected in an electronic oscillator circuit resonant mechanical vibrations in the device generate an oscillating signal of a specific frequency like the similar quartz crystal they are used in oscillators for purposes such as generating. The usually value is about 22pf between input and earth and the same between output and earth. 2 pin resonators don t have any in built capacitors so you will have to provide them yourself.

When using resonators with frequencies above 3 5 mhz the use of hs mode rather than xt mode is recommended hs mode may be used at any vdd for which the controller is rated. If fitting a 2 pin resonator or crystal you need to add two external capacitors one between each pin and 0v. Imagin you want to receive at 100mhz. Pic crystals in the passed i have used standard quartz crystals needing external caps does anyone know the pinout if these 3pin resonators.

Pin 16 is the rf input to the mixer and pin1 and pin2 is the local oscillator. The product comes out at pin 3. Ceramic resonators 2 pin ceramic resonators 3 pin ceramic resonators. 3 pin built in filter capacitor nominal oscillating frequency.

If hs is selected it is possible that the gain of the oscillator will overdrive the resonator. Practical use of ceramic filter in a receiver this receiver is mc3371.
