Note 1: Absolute Maximum Ratings are those values beyond which the life
of a device may be impaired.
Note 2: Input frequencies, f, are linearly phase shifted through the filter as
long as f
≤ fC; fC = cutoff frequency.
Figure 1 curve (A) shows the typical phase response of an LTC1264-7
operating at fCLK = 2.5MHz, fC = 100kHz. An endpoint straight line, curve
(B), depicts the ideal linear phase response of the filter. It is described by:
phase shift = 180
° – F (f/fC); f ≤ fC.
F is arbitrarily called the “phase factor” expressed in degrees. The phase
factor together with the specified deviation from the ideal straight line
allows the calculation of the phase at a given frequency. Note, the
maximum phase nonlinearity, Figure 1, occurs at the vicinity of f = 0.25 fC
and = 0.75 fC. Example: The phase shift at 70kHz of the LTC1264-7 shown
in Figure 1 is: phase shift = 180
° – 407° (70kHz/100kHz) ± nonlinearity =
–104.9
° ± 1% or –104.9°± 1.05°.
Note 3: Group delay and group delay deviation are calculated from the
measured phase factor and phase deviation specifications.
Note 4: The filter cutoff frequency is abbreviated as fCUTOFF or fC.
Note 5: The AC swing is typically 9VP-P, 5.6VP-P, 1.8VP-P with ±7.5V, ±5V,
±2.5V supply respectively. For more information refer to the THD + Noise
vs Input graphs.
