Description of Filter Functions
BANDPASS (Figure 12)
For all pole bandpass and lowpass filters (Butterworth,
Bessel, Chebyshev) use mode 1 if possible. If appropri-
ate fCLK/f0 or Q values are not available in mode 1,
mode 2 provides a selection that is closer to the
required values. Mode 1, however, has the highest
bandwidth (see Table 1). For pole-zero filters, such as
elliptics, see mode 3A.
HOBP = Bandpass output gain at
ω = ωo
f0 = ω0 / 2
π = The center frequency of the complex
pole pair. Input-output phase shift is -180° at f0.
Q = The quality factor of the complex pole pair.
Also the ratio of f0 to -3dB bandwidth of the
second-order bandpass response.
LOWPASS See bandpass text. (Figure 13)
HOLP = Lowpass output gain at DC
f0 = ω0 / 2
π
HIGHPASS (Figure 14)
Mode 3 is the only mode with a highpass output. It
works for all pole filter types such as Butterworth,
Bessel and Chebyshev. Use mode 3A for filters
employing both poles and zeros, such as elliptics.
HOHP = Highpass output gain as f approaches fCLK/4
f0 =
ω0 / 2π
NOTCH (Figure 15)
Mode 3A is recommended for multi-pole notch filters. In
second-order filters, mode 1 can also be used. The
advantages of mode 1 are higher bandwidth, com-
pared to mode 3 (higher fN can be implemented), and
no need for external components as required in mode
3A.
HON2 = Notch output gain as f approaches fCLK/4
HON1 = Notch output gain as f approaches DC
fn =
ωn / 2π
ALLPASS
Mode 4 is the only configuration in which an allpass
function can be realized.
