  1. Cable for UPAMD Steve Sedio Foxconn 8/02/2011

  2. 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

  3. Foxconn RecommendationSingle Ended Signal, Shield Made from Spiral (Power+ and Power -) Single Ended Signal Wire Insulation Inner Jacket Power + Power - & AC Ground Outer Jacket

  4. Add - Foxconn RecommendationBalanced Signal, Shield Made from Spiral (Power+ and Power -) Wire Insulation Balanced Signal pair Power + Inner Jacket Power - & AC Ground Outer Jacket
