  • Move probe to CLK output of ADN2814 CDS
  • Study datasheets for tempco or phase/delay specs
    • ADN2814: no obvious information, but it's pretty long and detailed so I may have missed something
    • SY89832: 300-500ps delay; 200ps risetime; no tempco information
    • SY89872: 450-700ps delay; 130ps risetime. There is a prop delay vs temp plot; 25ps over 60 deg C more or less linear (0.42ps/deg C)
    • DS91M125: 3-8ns delay; risetime 2ns per M-LVDS spec. There is a prop delay vs temp plot; slope is 10ps/deg C
