property frequency

Get/Set the output frequency value in Hz

This value represents the output frequency of the external VCO with respect to the input frequency reference.

property frequency_resolution

Get/Set the output frequency resolution value in Hz

This value represents the desired frequency resolution of the output frequency, used to derive modulus and fraction values for fractional-N operation.

property phase

Get/Set the phase adjust value in radians

Phase adjust increases the phase of the output relative to the current phase.

property powerdown

Get/Set the powerdown state

property locked

Get the PLL lock status

property muxout_select: muxout

Get/Set the MUXOUT pin function

This property uses register access, so it is mostly intended for debugging and testing purposes.

property charge_pump_index

Get/Set the charge pump current index value

This property uses register access, so it is mostly intended for debugging and testing purposes. The charge pump current value depends on the R_SET resistor value and the charge pump index value. The current charge pump current and resistor value can be set in the device-tree for production use-cases.

reg_read(reg: reg)

Direct Register Access via debugfs

reg_write(reg: reg, value)

Direct Register Access via debugfs
