10.APPENDIX A: EXTERNAL FILTERS
10.1
ADC Input Filter
The analog modulator samples the input at 6.144 MHz (internal MCLK=12.288 MHz). The digital filter will
reject signals within the stopband of the filter. However, there is no rejection for input signals which are
(n
×
6.144 MHz) the digital passband frequency, where n=0,1,2,...
Refer to Figure 24 for a recommended
analog input buffer that will attenuate any noise energy at 6.144 MHz, in addition to providing the optimum
source impedance for the modulators. The use of capacitors which have a large voltage coefficient (such
as general purpose ceramics) must be avoided since these can degrade signal linearity.
10.2
The CS42516 is a linear phase design and does not include phase or amplitude compensation for an ex-
ternal filter. Therefore, the DAC system phase and amplitude response will be dependent on the external
analog circuitry.
