ELECTRICAL CHARACTERISTICS

Note 1: Absolute Maximum Ratings are those values beyond which the life

of a device may be impaired.

= 2.5MHz

CLK C

CLK

(f /f ) = 25:1

Note 2: Input frequencies, f, are linearly phase shifted through the filter as

long as f ≤ f ; f = cutoff frequency.

Figure 1 curve (A) shows the typical phase response of an LTC1264-7

operating at f = 2.5MHz, f = 100kHz. An endpoint straight line, curve

–90

CLK

(B), depicts the ideal linear phase response of the filter. It is described by:

phase shift = 180° – F (f/f ); f ≤ f .

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

and = 0.75 f . 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 f

or f .

Note 5: The AC swing is typically 9V , 5.6V , 1.8V with ± 7.5V, ± 5V,

P-P
