STLC2150
Crystal oscillator
An on-chip crystal oscillator provides a 13MHz master clock. The external crystal must be connected to the pads
XTAL13I and XTAL13O.
The frequency specification of ±20 ppm can be achieved by 2 different ways:
The control word allows modifying the value of the capacitor connected to the oscillator pads. The total capac-
itance (including the parasitic capacitors) must be about 16 pF.
The variable capacitor is implemented as a capacitor array of about 255 x 90 fF.
External crystal example
1)
Low power clock
The STLC2150 can provide 3.2 or 32 KHz, low power clock for baseband chip operation in Hold, Snif and Park
modes.
External reference frequency
The STLC2150 can take a digital clock from external source 13 MHz on the CLK13MHZ pin.
The IC also can use an analogue (sine wave, from 0.2 up to 1 Vpp) clock from external 13 MHz source on the
XTAL13I pin.
Registers description
To provide operational control, configuration flexibility (e.g. clock configuration, XTAL trimming) and to set max-
imum performance the STLC2150 has a bank of registers. Detailed description is available in “STLC2150: In-
terface and Programming Guide”.
