FLT[1:0]
Digital Filter Roll-Off Control
These bits are Read/Write.
Default Value: 00B
FLT[1:0] = 00B
Sharp Roll-Off (default)
FLT[1:0] = 01B
Slow Roll-Off 1
FLT[1:0] = 10B
Slow Roll-Off 2
Bits FLT[1:0] allow the user to select the digital filter roll-off that is best suited to their application. Three filter
roll-off selections are available: Sharp, Slow 1, and Slow 2
The filter responses for these selections are shown in the Typical Performance Curves section of this data sheet.
Slow roll-off performance is specified for 8x interpolation (X4DS = 0) only.
X4DS
4x/8x Digital Interpolation Control
This bit is Read/Write.
Default Value: 0
X4DS = 0
8x Interpolation (default)
X4DS = 1
4x Interpolation, used for fS = 192kHz or 176.4kHz
Bit X4DS allows the user to select the oversampling rate of the digital interpolation filter. For sampling
frequencies up to 96kHz, 8x interpolation is used, while 4x interpolation is used for sampling frequencies,
greater than 96kHz.
