11. VCXO Voltage Control Input Circuit
The drawing below shows the VCXO control voltage input (VC_IN) circuit used for evaluation of VCXOs. The VCXO control voltage can
be applied using the J1 SMA connector, or using TP3/TP6. A simple RC circuit is included to low-pass filter any noise on the input. The
RC circuit components can be removed or modified as required for your application.
