Other Parts Discussed in Thread: CC430F5137
Hello everyone!
I'm working on a project using the CC430F5137. I was trying to figure out how long it takes for the CC430 to transmit a packet using the sync-word interrupts.
All the CLK's are sourced by the 26MHz radio oscillator and the timer module is running on 13MHz.
I was sending the exact same packet multiple times and measured the time between the sync word interrupt and the end of the transmission. The time is not constant, in fact it takes on two sequent values (eg. 2965 and 2966 CLK cycles). However I was expecting it to be constant, therefore I'm interested in reasons for this?
One possible reason I came up with is, that the frequencies of the UCS and the radio module, are not synchronous due to the frequency handling in the radio module (PLL etc.), however there is not information in the data-sheets. Maybe someone can confirm my assumption or can help me with further information?
Thanks a lot in advance!
