NOTES:
1. Unless otherwise noted, all specifications in this table apply to all processor
frequencies.
2. Crossing Voltage is defined as absolute voltage where rising edge of BCLK0 is equal to
the falling edge of BCLK1.
3. For Vin between 0 V and V
IH
.
4. Cpad includes die capacitance only. No package parasitics are included.
5. V
CROSS
is defined as the total variation of all crossing voltages as defined in note 2.
6. Measurement taken from differential waveform.
7. Measurement taken from single-ended waveform.
8. “Steady state” voltage, not including Overshoots or Undershoots.
9. Only applies to the differential rising edge (BCLK0 rising and BCLK1 falling).
