PARAMETER
TEST CONDITIONS
WAKE-UP AND TIMING
Power mode 1 → Active
Digital regulator on, 16-MHz RCOSC and 32-MHz crystal
oscillator off. Start-up of 16-MHz RCOSC
Power mode 2 or 3 → Active
Digital regulator off, 16-MHz RCOSC and 32-MHz crystal
oscillator off. Start-up of regulator and 16-MHz RCOSC
Active → TX or RX
Crystal ESR = 16 Ω. Initially running on 16-MHz RCOSC,

(1) 0.1% BER maps to 30.8% PER
(2) The receiver sensitivity setting is programmable using a TI BLE stack vendor-specific API command. The default value is standard
mode.
(3) Results based on standard gain mode
(4) Difference between center frequency of the received RF signal and local oscillator frequency
(5) Difference between incoming symbol rate and the internally generated symbol rate
