Notes:
1. Rise and fall times for the L3_CLK output are measured from 20% to 80% of GVDD.
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
the input L3_ECHO_CLKn (see Figure 10). Input timings are measured at the pins.
4. All output specifications are measured from the midpoint voltage of the rising edge of L3_CLKn to the midpoint of the signal
in question. The output timings are measured at the pins. All output timings assume a purely resistive 50-
Ω load (see
5. Assumes default value of L3OHCR. See Section 5.2.4.1, “Effects of L3OHCR Settings on L3 Bus AC Specifications,” for more
information.
