Notes:
1. Output specifications are measured from the 50% level of the rising edge of QE_CLK_IN to the 50% level of the signal.
Timings are measured at the pin.
2. The symbols used for timing specifications follow the pattern of t
(first two letters of functional block)(signal)(state)(reference)(state)
for
inputs and t
(first two letters of functional block)(reference)(state)(signal)(state)
for outputs. For example, t
SEKHOX
symbolizes the TDM/SI
outputs external timing (SE) for the time t
TDM/SI
memory clock reference (K) goes from the high state (H) until outputs (O)
are invalid (X).
