Dual 1.1Gbps Pin Electronics with Integrated
PMU and Level-Setting DACs
The VCH_, VCL_, and VIN_ DACs have duplicate calibra-
tion registers that are selected and addressed as a func-
tion of the selected DCL/PMU modes. The VCH_ and
VCL_ registers each have three separate calibration
registers that are used by the window comparator, the
differential comparator, and the PMU comparator,
respectively. The VIN_ register features six duplicate cali-
bration registers that are selected as a function of the
PMU force mode. These registers are individually
addressed by first selecting the appropriate mode, then
performing the register write. After the calibration regis-
ters are programmed, the appropriate register is automat-
ically switched in as a function of the operating mode.
Table 20 presents a list of the DAC registers and their
default values. Calibration registers are programmed to
default values only during a power-on reset. Asserting
RST does not force the calibration registers to their
default values. Table 21 summarizes the DAC register
addresses. Figure 13 shows how the calibration regis-
ters affect the DAC outputs.
