Electrical Specifications
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. Threshold Region is defined as a region entered about the crossing voltage in which the differential receiver
switches. It includes input threshold hysteresis.
4. For Vin between 0 V and V
H
.
5. Cpad includes die capacitance only. No package parasitics are included.
6. VCROSS is defined as the total variation of all crossing voltages as defined in note 2
