RsetN	Impedance Set Point, N Channel		40	70	Ω	2

Notes:

1. VREF is nominally set to 50% of VCC_CORE with actual values that are specific to motherboard design implementation. VREF must be created with a sufficiently accurate DC source and a sufficiently quiet AC response to adhere to the ± 50 mV specification listed

above.

2. Measured at VCC_CORE / 2.
