Reference Frequency Selection
The “LO2 In” and “LO2 Out” pins form a reference oscillator
when connected to an external parallel–resonant crystal. The
reference oscillator is also the second local oscillator for the
RF Receiver. Figure 114 shows the relationship between
different crystal frequencies and reference frequencies for
cordless phone applications in various countries. “LO2 In”
may also serve as an input for an externally generated
reference signal which is ac–coupled. The switched
capacitor filter 6–bit programmable counter must be
programmed for the crystal frequency that is selected since
this clock is derived from the crystal frequency and must be
held constant regardless of the crystal that is selected. The
actual switched capacitor clock divider ratio is twice the
programmed divider ratio due to the a fixed divide by 2.0 after
the programmable counter. The scrambler mixer modulation
frequency is the switched capacitor clock divided by 40 for
the MC13110A/B.
Mode Control Register
The power saving modes; mutes, disables, volume
control, and microprocessor clock output frequency are all
set by the Mode Control Register. Operation of the Control
