MODULATOR INTERFACE
1.
The 4 MHz clock drive to the MC44BS373 must be
filtered and the level set correctly. This can be achieved
simply by using a 1
H inductor and 1500 pF and series
750 ohm resistor and 100 pF blocking cap, as shown in
Figure 7 note 2.
2.
The MC44BS373 SPLL filter must be changed to a
single 2.2
F capacitor to ground. Please see Figure 7
note 3. (note some caps exhibit microphonic problems
in this application.
3.
Input impedance of the MC44BS373 is around
70 Kohms and to preserve the low frequency
performance the coupling caps should be greater than
0.1
