TUSB320LAI: What the capacitance of the TUSB320LAI ?

Part Number: TUSB320LAI

What the capacitance of the TUSB320LAI ?

In the data sheet for the TPD2S300 - In Table 5. CC Line Capacitor Calculation it states "TUSB422 capacitance 200 450 pF From the TUSB422 Datasheet" However I am using a TUSB320LAI - what is the equivalent parameter for this device ?

I couldn't find it in the TUSB320LAI Data Sheet ?

Hi Shmuel,

Unfortunately we do not have available the exact value for this parameter. However, the typical max cap spec for CC lines (in an order of hundred pF) and we are far less than that. In the TUSB320LAI, no cap was purposely put there, the cap on CC lines should be only be pad, ESD and parasitics, should be in an order of a few pF.

Thank you for your reply.

Please see the following as they sent me to you - In light of this what capacitor value should I use ?

Alternatively could you please speak to Aramis P. Alvarez directly to work out what value I should use if any ?
