Si10xx-DK
10.3. System Clock Sources
10.3.1. Internal Oscillators
The Si10xx or Si1010 device installed on the daughtercard features a factory calibrated programmable high-
frequency internal oscillator (24.5 MHz base frequency, ±2%) and a low power internal oscillator (20 MHz ±10%).
After each reset, the low power oscillator divided by 8 results in a default system clock frequency of 2.5 MHz
(±10%). The selected system clock and the system clock divider may be configured by software for operation at
other frequencies. For low-frequency operation, the Si10xx and Si1010 features a smaRTClock real time clock. A
32.768 kHz watch crystal (Y2) is included on the daughtercard. If you wish to operate the Si10xx device at a
frequency not available with the internal oscillators, an external crystal may be used. Refer to the Si100x or Si101x
data sheet for more information on configuring the system clock source.
10.3.2. External Oscillator Options
The daughtercards are designed to facilitate the installation of an external crystal (Y1). Install a 10 M resistor at
R9 and install capacitors at C20 and C21 using values appropriate for the crystal you select. If you wish to operate
the external oscillator in capacitor or RC mode, options to install a capacitor or an RC network are also available on
the target board. Populate C21 for capacitor mode, and populate R16 and C21 for RC mode. Refer to the Si100x-
Si101x data sheet for more information on the use of external oscillators.
10.4. Port I/O Headers (J2, J3, J4, J6)
Access to all Port I/O on the Si10xx is provided through the headers J2, J3, and J4. The header J6 provides access
to the ground plane for easy clipping of oscilloscope probes.
