TPS544C20: Cio at CLK(5pin) and Data(4pin) pins

Yasushi Fujiwara

Part Number: TPS544C20

Hello Experts,

My customer want to know about Cio of CLK(5pin) and DATA(4pin). I cannot found this in datasheet. This is needed to calculate total capacitance on SMBus of the system. Also does it vary by something else?

Best Regards,
Fujiwara

Fujiwara-san,

I doubt we have that data. I cannot think of any reason to intentionally introduce any internal capacitance. Any capacitance would be parasitic. It is possible a parasitic analysis was done. I will check for it tomorrow. If it exists, it may be difficult to locate.

Fujiwara-san,

My source suggests the capacitance is in the range of 2.5 - 5.0 pF
