TIMING CONVENTIONS
For the purposes of this timing specification the following
conventions apply
Input Signals
Period
Rise Time
Fall Time
Pulse Width High The high pulse width is designated as
Pulse Width Low
Setup Time
Hold Time
Delay Time
All input signals may be characterized
as V
t
The period of clock signal is
designated as t
represents the mnemonic of the clock
signal being specified
Rise times are designated as t
where yy represents a mnemonic of
the signal whose rise time is being
specified t
V
Fall times are designated as t
where yy represents a mnemonic of
the signal whose fall time is being
specified t
V
t
mnemonic of the input or output signal
whose pulse width is being specified
High pulse widths are measured from
V
The low pulse width is designated as
t
mnemonic of the input or output signal
whose pulse width is being specified
Low pulse widths are measured from
V
Setup times are designated as t
where ww represents the mnemonic of
the input signal whose setup time is
being specified relative to a clock or
strobe input represented by mnemonic
xx Setup times are measured from the
ww Valid to xx Invalid
Hold times are designated as t
where ww represents the mnemonic of
the input signal whose hold time is
being specified relative to a clock or
strobe input represented by mnemonic
xx Hold times are measured from xx
Valid to ww Invalid
Delay times are designated as t
Hi to Low where xx represents the
mnemonic of the input reference
signal and yy represents the
mnemonic of the output signal whose
timing is being specified relative to xx
The mnemonic may optionally be
terminated by an H or L to specify the
high going or low going transition of
the output signal Maximum delay
times are measured from xx Valid to yy
Valid Minimum delay times are
measured from xx Valid to yy Invalid
This parameter is tested under the
load conditions specified in the
Conditions column of the Timing
