Time from STROBE edge to negation of
DMARQ or assertion of STOP (when
sender terminates a burst)
Notes:
1) t
UI
, t
MLI
and t
LI
indicate sender -to-recipient or recipient-to-sender interlocks, that is, one agent (either
sender or recipient) is waiting for the other agent to respond with a signal before proceeding. t
UI
is an
unlimited interlock, that has no maximum time value. t
MLI
is a limited time-out that has a defined
minimum. t
LI
is a limited time-out, that has a defined maximum.
2) All timing parameters are measured at the connector of the device to which the parameter applies. For
example, the sender shall stop generating STROBE edges t
RFS
after the negation of DMARDY-. Both
STROBE and DMARDY- timing measurements are taken at the connector of the sender.
3) All timing measurement switching points (low to high and high to low) are to be taken at 1.5 V.
