The clock and data relationships for all output and input signals are illustrated in this
section. All signals and clocks listed are for one framer. The timings listed are
identical for all framers on-chip. Propagation delays for the output signals are listed
below. The output signal timings are relative to the listed edge of the clock. Output
and input signals relative to either the rising or the falling edge of the clock
(programmable) are listed with the edge as rising/falling. Clock outputs derived from
clock inputs are listed with the edge as both. In both cases, this means that the delay
number given applies for either edge. Input signals should have setup and hold times
with respect to the listed edge of the given input clock.
