LOCK OUTPUT DIVIDER
The crystal oscillator produces a reference frequency that
is divided and buffered to drive a microcontroller. Table 9
gives the division ratios. The buffer is a CMOS output
which can drive up to 20 pF at 10 MHz in both CLKO level
modes.
When the clock output signal is used, an external RC filter
connected to pin CLKOUT can be added to limit clock
waveform edges and therefore clock radiation on the
printed-circuit board.
To supply the clock to the microcontroller and save current
in the handset, an external low power resonator may be
used and the clock output disabled (000) as well as the
crystal oscillator (Xtal active = 0). In power saving mode,
the divider ratio can be programmed down to 128 to
reduce the microcontroller power consumption.
