Notes:
1. Timing
is
without
the
use
of
the
phase-locked
loops
(PLLs).
2. This
clock
delay
is
for
a
fully
routed
clock
tree
that
uses
the
secondary
clock
network.
It
includes
the
LVTTL
(3.3
V)
input
clock
buffer,
the
clock
routing
to
the
PIO
CLK
input,
the
clock
Q
of
the
FF,
and
the
delay
through
the
LVTTL
(3.3
V)
data
output
buffer.
An
SCLK
input
clock
can
be
at
any
input
pin.
3. For
timing
improvements
using
other
I/O
buffer
types
for
the
input
clock
buffer
or
output
data
buffer,
