Notes:
1. All outputs are measured from the midpoint voltage of the falling/rising edge of tTCLK 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 tTCLK.
5. Non-JTAG signal output timing with respect to tTCLK.
