Electrical Specifications
2.8.3
Phase Lock Loop (PLL) and Filter
An on-die PLL filter solution will be implemented on the processor. The VCCPLL input is
used for the PLL. Refer to
for DC specifications.
2.8.4
BCLK[1:0] Specifications
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
BCLK0 equals the falling edge of BCLK1.
3.
“Steady state” voltage, not including overshoot or undershoot.
4.
Overshoot is defined as the absolute value of the maximum voltage. Undershoot is defined
as the absolute value of the minimum voltage.
5.
Measurement taken from differential waveform.
