CS4270
5.1.4 Clock Ratio Selection
Depending on whether the CS4270 is in Master or Slave Mode, different MCKL/LRCK and SCLK/LRCK
ratios may be used. These ratios are shown in the
Table 2
.
5.1.5 Interpolation Filter
In Stand-Alone Mode, the fast roll-off interpolation filter is used. Filter specifications can be found in
Sec-
tion 3
. Plots of the data are contained in
Section 11. “Appendix” on page 42
.
5.1.6 High-Pass Filter
The operational amplifiers in the input circuitry driving the CS4270 may generate a small DC offset into
the ADC. The CS4270 includes a high-pass filter after the decimator to remove any DC offset which could
result in recording a DC level, possibly yielding "clicks" when switching between devices in a multichannel
system. In Stand-Alone Mode, the high-pass filter continuously subtracts a measure of the DC offset from
the output of the decimation filter This function cannot be disabled in Stand-Alone Mode.
