8. EXTERNAL FILTERS
8.1
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 mul-
tiples of the digital passband frequency (n
a recommended analog input filter that will attenuate any noise energy at 6.144 MHz, in addition to providing
the optimum source impedance for the modulators. Refer to
count passive input filters. The use of capacitors that have a large voltage coefficient (such as general-pur-
pose ceramics) must be avoided since these can degrade signal linearity
