External Resonator Coupling Port Information
The external resonator has to be an equivalent series resonance.
However, this impedance must also 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 tables. The diagrams show this impedance in a wider band. These
values don’t include the wire bonding (self L_erc given in the section “Typical
Assembly and Bias Configuration”).
