Appendix G
This appendix contains instructions for changing the active on-board oscillator for PLL1.
Changing from Crystal Resonator to VCXO
If the board has been setup to use the crystal-based oscillator with PLL1, the crystal may be disabled and
the VCXO enabled as described on the following pages:
1. Install a zero Ohm resistor in R79 (near the VCXO)
