TMDS570LS31HDK: Load Capacitance Calculation

Part Number:TMDS570LS31HDK

Hi Team,

I have a question on the calculation of load capacitance provided in the Hercules EVM (http://www.ti.com/tool/TMDS570LS31HDK ).

The load capacitance was spec'd at 10pF (C27/28), however, the 7A-16.000MAAJ crystal (https://www.mouser.com/datasheet/2/417/7a-13881.pdf ) specifies the load cap ~ 18pF and strap cap of ~ 5pF.

Can you share some insights as how 10pF was obtained? Shouldn't C27/28 be ~36-26pF, according to this post: https://e2e.ti.com/support/microcontrollers/hercules/f/312/t/667495?TMS570LS0432-Resonator-Selection

Thanks,
Mitchell
