This value can be used to calculate the in-band phase noise for any operating frequency. Use the following equation to calculate the in-band phase noise performance
as seen at the power amplifier (PA) output: −203 + 10 log(f
Guaranteed by design. Sample tested to ensure compliance.
A TCXO, VCXO, or OCXO can be used as an external oscillator.
Crystal start-up time is the time from chip enable (CE) being asserted to correct clock frequency on the CLKOUT pin.
