Figure 9.3: Crystal Driver Circuit
Figure 9.4 shows an electrical equivalent circuit for a crystal. The crystal appears inductive near its resonant
frequency. It forms a resonant circuit with its load capacitors.
Figure 9.4: Crystal Equivalent Circuit
The resonant frequency may be trimmed with the crystal load capacitance. BlueCore4-ROM contains variable internal
capacitors to provide a fine trim.
