Processor Bus AC
Specifications
Table 13 provides the processor bus AC timing specifications for the PC755 as defined
in Figure 11 and Figure 13. Timing specifications for the L2 bus are provided in Section
“L2 Clock AC Specifications page 28.
Notes:
1. All input specifications are measured from the midpoint of the signal in question to the midpoint of the rising edge of the input
SYSCLK. All output specifications are measured from the midpoint of the rising edge of SYSCLK to the midpoint of the sig-
nal in question. All output timings assume a purely resistive 50
load (See Figure 11). Input and output timings are
measured at the pin; time
-
of
flight delays must be added for trace lengths, vias, and connectors in the system.
2. THe symbology used for timing specifications herein follows the pattern of t
(signal)(state)(reference)(state)
for inputs and
t
(reference)(state)(signal)(state)
for outputs. For example, t
IVKH
symbolizes the time input signals (I) reach the valid state (V) relative
to the SYSCLK reference (K) going to the high (H) state or input setup time. And t
KHOV
symbolizes the time from SYSCLK(K)
going highs) until outputs (O) are valid (V) or output valid time. Input hold time can be read as the time that the input signal
(I) went invalid (X) with respect to the rising clock edge (KH)
-
note the position of the reference and its state for inputs
–
and
output hold time can be read as the time from the rising edge (KH) until the output went invalid (OX). For additional explana-
tion of AC timing specifications in Motorola PowerPC microprocessors, see the application note “Understanding AC Timing
Specifications for PowerPC Microprocessors.”
3. The setup and hold time is with respect to the rising edge of HRESET (see Figure 11).
4. This specification is for configuration mode select only. Also note that the HRESET must be held asserted for a minimum of
255 bus clocks after the PLL re
-
lock time during the power
-
on reset sequence.
5. t
SYSCLK
is the period of the external clock (SYSCLK) in nanoseconds (ns). The numbers given in the table must be multiplied
by the period of SYSCLK to compute the actual time duration (in nanoseconds) of the parameter in question.
6. Mode select signals are BVSEL, L2VSEL, PLL_CFG[0
-
3]
7. Guaranteed by design and characterization.
8. Bus mode select pins must remain stable during operation. Changing the logic states of BVSEL or L2VSEL during operation
will cause the bus mode voltage selection to change. Changing the logic states of the PLL_CFG pins during operation will
cause the PLL division ratio selection to change. Both of these conditions are considered outside the specification and are
not supported. Once HRESET is negated the states of the bus mode selection pins must remain stable.
Figure 11 provides the mode select input timing diagram for the PC755.
