Input Connections
The analog modulator samples the input at 6.144 MHz (MCLK=12.288 MHz). The digital filter will reject signals with-
in 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 12 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. Figure 13 shows the full-scale analog input levels.
