L3_CLK to high impedance: Data and parity
L3_CLK to high impedance: All other outputs
Notes:
1. Rise and fall times for the L3_CLK output are measured from 20% to 80% of GV
2. Timing behavior and characterization are currently being evaluated.
3. All input specifications are measured from the midpoint of the signal in question to the midpoint voltage of the rising edge of
4. All output specifications are measured from the midpoint voltage of the rising edge of L3_CLKn to the midpoint of the signal
5. Assumes default value of L3OHCR. See
the input L3_ECHO_CLKn (see
in question. The output timings are measured at the pins. All output timings assume a purely resistive 50-Ω load (see
