System clock
The STLC2500A works with a single clock (sine wave or digital) provided on the
RF_CLK_IN pin. Precision of this clock should be 20 ppm. The external STLC2500A clock
could be 13 or 26 MHz (for GSM application), 19.2 MHz and 38.4 MHz (for 2.5 & 3G &
CDMA platforms).
6.4
Low power clock
The low power clock is used by the Bluetooth Controller as reference clock during the low
power modes. It requires an accuracy of 250ppm. The external STLC2500A clock, provided
on the LP_CLK digital pin could be 3.2 kHz, 16.384 kHz, 32 kHz and 32.768 kHz.
