Description
Output polarity. Setting this bit inverts the HSTL driver output polarity.
Reserved.
HSTL output doubler.
01 = doubler disabled.
10 = doubler enabled. When using doubler, Bit 5 in Register 0x0010 must also be set to 1.
Description
This bit allows the user to select whether the CMOS driver output is divided by the S-divider.
0 = S-divider input sent to CMOS driver.
1 = S-divider output sent to CMOS driver. See Figure 39.
Description
DAC full-scale current, Bits[7:0]. See the Digital-to-Analog (DAC) Output section.
Description
DAC full-scale current, Bits[9:8]. See Register 0x040B.
Description
Harmonic Spur Reduction A enable.
Setting this bit doubles the gain of the cancelling circuit and also doubles the minimum step size.
Reserved.
Spur A Harmonic 1 to Spur A Harmonic 15. Allows user to choose which harmonic to eliminate.
Description
Linear multiplier for Spur A magnitude.
