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 Table 5 for DC specifications.

Crossing voltage is defined as the instantaneous voltage value when the rising edge of BCLK0

equals the falling edge of BCLK1.

VHavg is the statistical average of the VH measured by the oscilloscope.

The crossing point must meet the absolute and relative crossing point specifications

simultaneously.

Overshoot is defined as the absolute value of the maximum voltage. Undershoot is defined as

the absolute value of the minimum voltage.
