RSL - Transmit Timing
Figure 55 is a timing diagram which shows the detailed
requirements for the RSL output signals on the Channel.
The DQA and DQB signals are outputs to transmit informa-
tion that is received by a Direct RAC on the Channel. Each
signal is driven twice per t
CYCLE
interval. The beginning
and end of the even transmit window is at the 75% point of
the previous cycle and at the 25% point of the current cycle.
The beginning and end of the odd transmit window is at the
25% point and at the 75% point of the current cycle. These
transmit points are measured relative to the crossing points
of the falling CTM clock edge. The size of the actual
transmit window is less than the ideal t
CYCLE
/2, as indicated
by the non-zero values of t
Q,MIN
and t
Q,MAX
. The t
Q
param-
eters are measured at the 50% voltage point of the output
transition.
The t
QR
and t
QF
rise- and fall-time parameters are measured
at the 20% and 80% points of the output transition.
