2.4 Clocking

The BoosterPack™ plug-in module provides a 32.768kHz oscillator (Y2) component for slow clock input to the CC33X1MOD device.

If the user desires to provide their own external slow clock through the Slow Clock Input pin (P2.19), then some rework must be performed. The Y2 oscillator needs to be removed, and a 0201 sized 0-ohm resistor be populated on R29 pad. See Figure 2-8. The slow clock can also be generated internally to save on BOM.
