3. TECHNICAL BRIEF
3.4 Crystal(26 MHz, X102)
The X-GOLDTM110 RF-Subsystem contains a fully
integrated 26 MHz digitally controlled crystal
oscillator,
designed for 8 pF crystals. The only external part
of the oscillator is the crystal itself. Overall pulling
range of the
DCXO is approximately 55 ppm, controllable
by a 13-bit tuning word DCXO_AFC[16:4].
The 26 MHz reference clock can also be applied
to external components like Bluetooth or GPS, via
the buffered output signal FSYS1.
