Notes:
1 All outputs are measured from the midpoint voltage of the falling/rising edge of t
TCLK to the midpoint of the signal in question.
The output timings are measured at the pins. All output timings assume a purely resistive 50
Ω load (see Figure 17).
Time-of-flight delays must be added for trace lengths, vias, and connectors in the system.
2 The symbols used for timing specifications herein follow the pattern of t
(first two letters of functional block)(signal)(state) (reference)(state)
for inputs and t(first two letters of functional block)(reference)(state)(signal)(state) for outputs. For example, tJTDVKH symbolizes JTAG
device timing (JT) with respect to the time data input signals (D) reaching the valid state (V) relative to the tJTG clock
reference (K) going to the high (H) state or setup time. Also, tJTDXKH symbolizes JTAG timing (JT) with respect to the time
data input signals (D) went invalid (X) relative to the tJTG clock reference (K) going to the high (H) state. Note that, in general,
the clock reference symbol representation is based on three letters representing the clock of a particular functional. For rise
and fall times, the latter convention is used with the appropriate letter: R (rise) or F (fall).
3 TRST is an asynchronous level sensitive signal. The setup time is for test purposes only.
4 Non-JTAG signal input timing with respect to t
TCLK.
5 Non-JTAG signal output timing with respect to t
TCLK.
