External Resonator Coupling Information

The external resonator has to be an equivalent band-pass filter with 180°

insertion phase at resonance (oscillation) frequency. However, this filter must be

compatible to the loop parameters of the oscillator (between ERC ports) in order

to obtain the oscillation conditions and to avoid parasitic oscillations. The

following information concerns the S parameters of the chip (plots for S21 and

tables for the four parameters), reference ports are ERC1 and ERC2. These

values don’t include the wire bonding equivalent inductance L_erc1 and L_erc2

given in section “Typical Assembly and Bias Configuration”. For more detail and

for a wider band analysis a complete S parameter file is available on request.
