Dear all, I have HDMI connections from IC to connector through a common-mode choke. HDMI differential signals requires Zdiff = 100ohm+/-15%. I am wondering if this Zdiff = 100ohm+/-15% is for bare board or for effective impedance (after mounting the IC, choke and connector)? How to include the loading effects of IC, choke and connector in Zdiff calculation? Please advise. Thank you very much in advance. -- Regards, Chai _________________________________________________________________ Using a handphone prepaid card?
