adi_adrv9025_CfrHardClipperConfigSet(...)
int32_t adi_adrv9025_CfrHardClipperConfigSet(adi_adrv9025_Device_t *device,
adi_adrv9025_CfrHardClipperConfig_t cfrHardClipperConfig[], uint8_t
cfrHardClipperCfgArraySize);
This function enables/disables the CFR hard clipper and configures the hard clipper threshold
Description
The CFR hard clipper threshold is applied to an approximation of
dBFS which means that a threshold of 1 corresponds to a threshold of 0 dBFS. ADI recommends not setting the hard clipper
threshold to a value less than -7 dBFS in order to ensure optimum performance.
This function may be called any time after device initialization and the ARM boot up is complete. The hard clipper setting is
Precondition
currently an init time setting and has to be setup before running the CFR init cal. There is no support for dynamically changing
the hard clipper threshold during runtime.
