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-
load (see Figure 10).
5. tL3_CLK/4 is one-fourth the period of L3_CLKn. This parameter indicates that the specified output signal is actually
launched by an internal clock delayed in phase by 90°. Therefore, there is a frequency component to the output valid
and output hold times such that the specified output signal will be valid for approximately one L3_CLK period
starting three-fourths of a clock before the edge on which the SRAM will sample it and ending one-fourth of a clock
period after the edge it will be sampled.
6. Assumes default value of L3OHCR. See Section 1.5.2.4.1, “Effects of L3OHCR Settings on L3 Bus AC
Specifications” for more information.
