BCLK[1:0] Specifications (CK505 based Platforms)
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.
BCLK0 equals the falling edge of BCLK1.
3.
V
Havg
is the statistical average of the V
H
measured by the oscilloscope.
4.
"Steady state" voltage, not including overshoot or undershoot.
5.
Overshoot is defined as the absolute value of the maximum voltage. Undershoot is defined
as the absolute value of the minimum voltage.
as the absolute value of the minimum voltage.
6.
Measurement taken from differential waveform.
7.
The crossing point must meet the absolute and relative crossing point specifications
simultaneously.
simultaneously.
8.
Cpad includes die capacitance only. No package parasitics are included.
