DEMOD_VALID
DATA-Pin 22 CLK-Pin 4 VALID-Pin 23 Outputs
These are the digital demodulation data output signal, the digital demodulation
clock output signal, and the digital demodulation valid output signal. These signals
are connected directly in parallel with their respective front-panel connectors.

FP_DATA,
FP_CLOCK
DATA-Pin 1 CLOCK-Pin 20 Inputs
These are the front-panel DATA, and CLOCK inputs. These signals are connected
directly in parallel with their respective front-panel connectors.
NOTE The two inputs are directly coupled to each other. Avoid putting signals on both
inputs simultaneously.
