Processor AC Timing Waveforms
The following figures are used in conjunction with the AC timing tables,

Note:
through
, the following apply:
1. All common clock AC timings for AGTL+ signals are referenced to the Crossing Voltage
(V
CROSS
) of the BCLK[1:0] at rising edge of BCLK0. All common clock AGTL+ signal
timings are referenced at GTLREF at the processor core.
2. All source synchronous AC timings for AGTL+ signals are referenced to their associated
strobe (address or data) at GTLREF. Source synchronous data signals are referenced to the
falling edge of their associated data strobe. Source synchronous address signals are referenced
to the rising and falling edge of their associated address strobe. All source synchronous
AGTL+ signal timings are referenced at GTLREF at the processor core silicon.
falling edge of their associated data strobe. Source synchronous address signals are referenced
to the rising and falling edge of their associated address strobe. All source synchronous
AGTL+ signal timings are referenced at GTLREF at the processor core silicon.
3. All AC timings for AGTL+ strobe signals are referenced to BCLK[1:0] at V
CROSS
. All
AGTL+ strobe signal timings are referenced at GTLREF at the processor core silicon.
4. All AC timings for the TAP signals are referenced to the TCK signal at 0.5*VCC at the
processor pins. All TAP signal timings (TMS, TDI, etc) are referenced at 0.5*VCC at the
processor pins.
