This section describes the AC electrical specifications for the IEEE 1149.1 (JTAG) interface.
provides the JTAG AC timing specifications as defined in

At recommended operating conditions (see
JTAG external clock frequency of operation
JTAG external clock cycle time
JTAG external clock pulse width measured at 1.4 V
JTAG external clock rise and fall times
TRST assert time
Input setup times:
Input hold times:
Valid times:
Output hold times:
JTAG external clock to output high impedance:
Notes:
1. All outputs are measured from the midpoint voltage of the falling/rising edge of t
2. The symbols used for timing specifications herein follow the pattern of t
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
5. Non-JTAG signal output timing with respect to t
6. Guaranteed by design and characterization.
The output timings are measured at the pins. All output timings assume a purely resistive 50-Ω load (see
Time-of-flight delays must be added for trace lengths, vias, and connectors in the system.

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).
