The BPF2 User Module uses two switched-capacitor blocks to implement a general-purpose second order band-pass filter. Center frequency and Q are functions of the ratios of programmable on-chip capacitors and clock frequency; no external components are required. The user selects filter characteristics and clock frequency. Capacitor and clock divider values are automatically calculated in the design tool (wizard). BPF2 can be cascaded or combined with other filter types to make more complex filter structures.
