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, tHIKHOX symbolizes the outputs
internal timing (HI) for the time tserial memory clock reference (K) goes from the high state (H) until outputs (O) are invalid (X).
