RECEIVER DE-EMPHASIS CONTROL (RCVR_DEM)
Default = 0
Function:
Receiver Mode Control (address 1Eh) register to set the appropriate sample rate.
When enabled, de-emphasis will be automatically applied when emphasis is detected based on the
channel status bits. The appropriate digital filter will be selected to maintain the standard 15µs/50µs
digital de-emphasis filter response at the auto-detected sample rate of either 32, 44.1, or 48 kHz. If
the FRC_PLL_LK bit is set to a ‘1’b, then the auto-detect sample rate feature is disabled. To apply
the correct de-emphasis filter, use the DE-EMPH bits in the Receiver Mode Control (address 1Eh)
register to set the appropriate sample rate.
