NSR Control (Register 0x3C)
Bits[7:4]—Reserved
Bits[3:1]—NSR Mode
Bits[3:1] determine the bandwidth mode of the NSR. When
Bits[3:1] are set to 000, the NSR is configured for a 22% BW
mode that provides enhanced SNR performance over 22% of
the sample rate. When Bits[3:1] are set to 001, the NSR is con-
figured for a 33% BW mode that provides enhanced SNR
performance over 33% of the sample rate.
Bit 0—NSR Enable
The NSR is enabled when Bit 0 is high and disabled when Bit 0
is low.
NSR Tuning Word (Register 0x3E)
Bits[7:6]—Reserved
Bits[5:0]—NSR Tuning Word
The NSR tuning word sets the band edges of the NSR band. In
22% BW mode, there are 57 possible tuning words; in 33% BW
mode, there are 34 possible tuning words. For either mode, each
step represents 0.5% of the ADC sample rate. For the equations
that are used to calculate the tuning word based on the BW
mode of operation, see the Noise Shaping Requantizer (NSR)
section.
SYNC Pin Control (Register 0x59)
Bits[7:2]—Reserved
Bit 1—SYNC Pin Sensitivity
If Bit 1 is set to a 0, the SYNC input responds to a level. If this
bit is set to high, the SYNC input responds to the edge (rising or
falling) set in Bit 0 of Address 0x59.
Bit 0—SYNC Pin Edge Sensitivity
If Bit 1 is set high, setting Bit 0 to a 0 causes the SYNC input to
respond to a falling edge. Likewise, if Bit 0 is set to 1, the SYNC
input responds to a rising edge.
