External Resonator Coupling Information

The external resonator has to be an equivalent series resonance. However, this

impedance must be compatible to the negative impedance of the oscillator ERC

port in order to obtain the oscillation conditions and to avoid parasitic oscillations.

Typical impedance of ERC port (Zerc) is given in the following table. The

diagram shows this impedance in a wider band. These values don’t include the

wire bonding (self L_erc given in the previous section).

The recommended external resonator properties are:

• series equivalent resonance

• highest possible Q (dielectric resonator, cavity ...) if no tuning

bandwidth required

• resistance at resonant frequency lower than 20Ω

• out-off band impedance has to be designed to avoid parasitic oscillation.
