# Decoupling Capacitor Calculation

I have few questions related to the schematics(BBB_SCH) sheet 2 in link

1. There is a bulk decoupling capacitor of 10uF,10V connected to the pin 10(AC) of the PMIC tps65217.pdf. Can some one please explain how is this value calculated now I know C = I * dt/dv but where in the data sheet can I find I , dt , dv.
2. There is a 100K ohm register R1 on the INT pin number 45. Can some one please let me know how is this value calculated.
3. Also on sheet 3 there is a SN74AUC1G74 which is connected to the CEC Clock for HDMI Framer. Can some please let me know is this a clock for the HDMI.

Regards

Nick
