Application information The slow input rise and fall times cause additional power dissipation, which can be calculated using the following formula: Padd = fi x (tr x ΔICC(AV) + tf x ΔICC(AV)) x VCC where: • • • • • Padd = additional power dissipation (μW); fi = input frequency (MHz); tr = input rise time (ns); 10 % to 90 %; tf = input fall time (ns); 90 % to 10 %; ΔICC(AV) = average additional supply current (μA). ΔICC(AV) differs with positive or negative input transitions, as shown in Fig. 11. For XC7WT14 used in relaxation oscillator circuit, see Fig. 12. Note to the application information: 1.
