6.4.6.2 Power-on and Data Clock (DCLK)
Many applications use the DCLK output for a system clock. For the ADC12D1800RF, each I- and Q-
channel has its own DCLKI and DCLKQ, respectively. The DCLK output is always active, unless that
channel is powered-down or the DCLK Reset feature is used while the device is in Demux Mode. As the
supply to the ADC12D1800RF ramps, the DCLK also comes up, see this example from the
ADC12D1800RFRB: Figure 6-15. While the supply is too low, there is no output at DCLK. As the supply
continues to ramp, DCLK functions intermittently with irregular frequency, but the amplitude continues to
track with the supply. Much below the low end of operating supply range of the ADC12D1800RF, the
DCLK is already fully operational.
