I have an A/V system which takes two balanced audio inputs, two DC inputs (8.4v and 12v), and outputs HDMI and IEEE-1394.
We frequently plug and unplug the system. Each of those connectors is at a different physical location on the rig. It would be nice to plug and unplug a single cable.
I was thinking of cutting the ends off the existing cables (25 ft) and using a multi-pin circular connector, but I'm worried that using this type of connector will degrade the high-speed interfaces. I know another poster had no problems using other connectors for USB.
HDMI has a max pixel clock rate of 165MHz up through revision 1.2. IEEE-1394 uses a 98.304 Mbit/sec half duplex data transport (roughly 98Mhz per channel?).
Is the inductance and capacitance between pins of an HDMI cable assembly mostly a function of the cable itself, or do the connectors play a significant role?
