Cable for UPAMD Steve Sedio Foxconn 8/02/2011
Requirements: • Power, 25 milliohms max • AWG selected by worst case resistance and operation at 50C • Signal • Option #1, Single ended – 50 – 60 ohms • Option #2, Balanced – 100 – 120 ohms • Data rate frequency, 500KHz • Power - is also RF ground (no separate ground). Drain wires would tie to power – in the plug. • Waiting for capacitance / inductance
