Notes:

  1. Unless otherwise noted, all specifications in this table apply to all processor frequencies.
  2. Crossing Voltage is defined as the instantaneous voltage value when the rising edge of BCLK(0/1/2/3)_​DN is equal to the falling edge of BCLK(0/1/2/3)_​DP.
  3. VHavg is the single ended average voltage when BCLK is driven high.
  4. The crossing point must meet the absolute and relative crossing point specifications simultaneously.
  5. VHavg can be measured directly using “Vtop”, “High” or other similar knob/feature in oscilloscopes.
  6. VCROSS DELTA is defined as the total variation of all crossing voltages as defined in Note 2.
  7. For Vin between 0 and Vih.
  8. Specifications can be validated at the pin.
