Preliminary Data Sheet
Figure 15
In this mode a 2.048 MHz system clock is provided at either the RFCLKF, RFCLKN or
the RFCLKEX pin. The VCXO and VCO supply the operating clocks for the SIDEC.
SDECO can be connected to slave. The feedback from SCLKO to SCLKI in order to
generate a control voltage for the 32 MHz VCO makes only sense if SCLKO is derived
from CLK16. The SDECI initializes the counter.
