Dear LimeSDR community and @Zack,
I would like to use the current 30.72 MHz oscillator mentioned above (XO2, Rakon E5280LF, LimeSDR-USB 1v4). However, I assume both Oscillators (XO1 and XO2) are mixed up in the schematic (see question at the end).
I contacted Rakon and they send me the official datasheet for the E5280LF 30.720 MHz TCVCXO. If you look at the datasheet (page3) it shows the following outline:
But on the board the oscillator looks different:
I assume a mistake in the schematic. It shows two oscillators: The XO2 and the XO1 (marked as NF):
The XO1 (E6245LF, RAKON_RPT7050A) might be the right one, as it looks exactly as on the board:
1. Question: Could it be that the two components have been mixed up and the XO2 should be NF?
2. Question: If not, what is the reason for chose the XO2 vs. XO1?
Sorry for re-activating the thread and thank you!
