4.3 Bluetooth LE RF Performance
All parameters in this section that are fast-clock dependent are verified using a 26-MHz XTAL under a
temperature range from –20°C to 70°C and an RF load of 50 Ω at the BT_RF port.

(1) Sensitivity degradation up to 3 dB may occur where the BLE frequency is a harmonic of the fast clock.
(2) Numbers show wanted signal-to-interfering signal ratio. Smaller numbers indicate better C/I performance.
