Serial operation. Time from sampling the
TX latency 8 Bits data on the transmitter data input pin until it
is observed on the RF output ports.
(1) Note that close-in spurs vary with centre frequency and limits the frequencies and output power level which the CC1150 can operate at
without violating regulatory restrictions. See also
Section 6.2.5 for information regarding additional filtering.
