The SINC4 digital filter provides greater than 120dB nor-
mal mode rejection at all frequencies except DC and
integer multiples of the modulator sampling frequency
(fS). The LTC2480’s autocalibration circuits further sim-
plify the antialiasing requirements by additional normal
mode signal filtering both in the analog and digital domain.
Independent of the operating mode, fS = 256 fN = 2048
fOUTMAX where fN is the notch frequency and fOUTMAX is
the maximum output data rate. In the internal oscillator
mode with a 50Hz notch setting, fS = 12800Hz, with
50Hz/60Hz rejection, fS = 13960Hz and with a 60Hz notch
setting fS = 15360Hz. In the external oscillator mode, fS =
fEOSC/20. The performance of the normal mode rejection
is shown in Figures 30 and 31.
In 1x speed mode, the regions of low rejection occurring
at integer multiples of fS have a very narrow bandwidth.
Magnified details of the normal mode rejection curves are
shown in Figure 32 (rejection near DC) and Figure 33
(rejection at fS = 256fN) where fN represents the notch
frequency. These curves have been derived for the exter-
nal oscillator mode but they can be used in all operating
modes by appropriately selecting the fN value.
The user can expect to achieve this level of performance
using the internal oscillator as it is demonstrated by Fig-
ures 34, 35 and 36. Typical measured values of the normal
mode rejection of the LTC2480 operating with an internal
oscillator and a 60Hz notch setting are shown in Figure 34
