TCA9617B: DDC Capacitance

Part Number: TCA9617B

What would be the expected capacitance measured on the slave side of the TCA9617B?  I'm seeing a higher than expected capacitance when I run the HDMI 1.4B DDC capacitance test.

Thanks!

    Hello JMMN,
    We have seen this before, but the failure is an artifact of the test method and isn't the true capacitance of the net. Do you have a schematic of the circuit. I need to know if they have the A side or B side attached to the cable.
