Figure 3. Jitter Test Configuration for an LVTTL Input Driving CDC421xxx
For the cases of the CDC421xxx being referenced by an external, clean LVCMOS input of 31.25 MHz, 33.33
MHz and 35.4167 MHz, the following tables list the measured SSB phase noise of all the outputs supported by
the CDC421xxx device, (100 MHz, 106.25 MHz, 125 MHz, 156.25 MHz, 212.5 MHz, 250 MHz, and 312.5 MHz)
from 100 Hz to 20 MHz from the carrier.
