Subject
The period of time during which the data must be valid in order to capture it correctly. The setup
and hold times determine the ideal strobe position within the sampling window:
Timing Diagram
The JEDEC standard for SSTL and HSTL I/O standards define both the AC and DC input signal
values. The AC values indicate the voltage levels at which the receiver must meet its timing
specifications. The DC values indicate the voltage levels at which the final logic state of the
receiver is unambiguously defined. After the receiver input has crossed the AC value, the receiver
changes to the new logic state.
The new logic state is then maintained as long as the input stays beyond the AC threshold. This
approach is intended to provide predictable receiver timing in the presence of input waveform
ringing:
Single-Ended Voltage Referenced I/O Standard
High-speed receiver and transmitter input and output clock period.
The timing difference between the fastest and slowest output edges, including t
clock skew, across channels driven by the same PLL. The clock is included in the TCCS
measurement (refer to the Timing Diagram figure under S in this table).
High-speed I/O block: Duty cycle on the high-speed transmitter output clock.
Timing Unit Interval (TUI)
The timing budget allowed for skew, propagation delays, and data sampling window.
(TUI = 1/(Receiver Input Clock Frequency Multiplication Factor) = t
Signal high-to-low transition time (80-20%)
Cycle-to-cycle jitter tolerance on the PLL clock input.
Period jitter on the general purpose I/O driven by a PLL.
Period jitter on the dedicated clock output driven by a PLL.
Signal low-to-high transition time (20-80%).
