Timing Parameter Symbology
Timing parameter symbols used are created in accordance with JEDEC Standard 100. To shorten the
symbols, some of the pin names and other related terminology have been abbreviated as follows:
Lowercase subscripts and their meanings:
a
access time
c
cycle time (period)
d
delay time
f
fall time
h
hold time
r
rise time
su
setup time
t
transition time
v
valid time
w
pulse duration (width)
Letters and symbols and their meanings:
H
High
L
Low
V
Valid
X
Unknown, changing, or don’t care level
Z
High impedance

General Notes on Timing Parameters
All output signals from the 28x devices (including XCLKOUT) are derived from an internal clock such that all
output transitions for a given half-cycle occur with a minimum of skewing relative to each other.
The signal combinations shown in the following timing diagrams may not necessarily represent actual cycles.
For actual cycle examples, see the appropriate cycle description section of this document.

NOTE: The data sheet provides timing at the device pin. For output timing analysis, the tester pin electronics and its transmission line effects
must be taken into account. A transmission line with a delay of 2 ns or longer can be used to produce the desired transmission line effect.
The transmission line is intended as a load only. It is not necessary to add or subtract the transmission line delay (2 ns or longer) from
the data sheet timing.
Input requirements in this data sheet are tested with an input slew rate of < 4 Volts per nanosecond (4 V/ns) at the device pin.
