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 signal
in question. All output timings assume a purely resistive 50-
Ω load (see Figure 5). 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, tIVKH 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 tKHOV symbolizes the time from SYSCLK
(K) going high (H) 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).
3. The setup and hold time is with respect to the rising edge of HRESET (see Figure 4).
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-relock time during the power-on reset sequence.
5. tsysclk is the period of the external clock (SYSCLK) in ns. The numbers given in the table must be multiplied by the period of
SYSCLK to compute the actual time duration (in ns) of the parameter in question.
6. Mode select signals are BVSEL, L2VSEL, PLL_CFG[0:3], and TLBISYNC.
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.
