2.5 Crystal Oscillator

All devices, except CC13x0 devices, require a 48MHz high frequency (HF) crystal to generate the reference clock for the radio (XOSC-HF). The CC13x0 devices require a 24MHz HF crystal (for XOSC-HF). The radio does not operate without this external crystal.

The higher-frequency crystal makes sourcing physically small crystals within the CC131x and CC135x specification requirements easier. Application note, Crystal Oscillator and Crystal Selection for the CC13xx, CC26xx, and CC23xx Family of Wireless MCUs, contains detailed information about the crystal oscillators for the CC devices discussed in this document, including information about how to select an appropriate crystal for the design.

Refer to the crystal requirements outlined in the device data sheet.
