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.
