Table 21. Transition Time Definition Transition State x -> y Crystal Oscillator Startup Time, Parameter 5.10 PLL Timing Receiver Preamble Time1 NOTES: 1 See Section 11.2.3, “Frame Format.” Receiver On-to-Off Time, Parameter 1.12 Standby to SPI running, state 60 -> 1 √ Standby to receiver running, states 5 -> 5b, 20 -> 21 √ Lock time parameter 5.9 √ Off to receiver running, states 0 -> 0b, 10 -> 11 √ Lock time parameter 5.9 √ Configuration to receiver running, states 1 -> (0b, 5b, 11, 21) 0 or lock time parameter 5.1 or lock time parameter 5.9 2 2 Depending on the PLL status before entering configuration mode. For example, the transition time from standby to receiver running (FSK modulation, 19.2 kBd, AFFC = 0, data manager enabled) is: 0.6 ms + 50 µs + (3 + 1)/19.2k = 970 µs. √ Receiver running to configuration mode, state (0b, 5b, 11, 12, 13, 21, 22, 23) -> 1, When CONFB=0, the transition from receive mode to configuration mode is immediate. Receiver running to standby mode, state 5b -> 5, (21, 22, 23) -> 20 √ Receiver running to off mode, state 0b -> 0, (11, 12, 13) -> 10 √ |
