Notes:
1. Rise and fall times for the L2SYNC_IN input are measured from 20% to 80% of L2OVDD.
2. All input specications are measured from the midpoint of the signal in question to the midpoint voltage of the rising
edge of the input L2SYNC_IN (see Figure 8). Input timings are measured at the pins.
3. All output specications are measured from the midpoint voltage of the rising edge of L2SYNC_IN 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).
4. The outputs are valid for both single-ended and differential L2CLK modes. For pipelined registered synchronous
BurstRAMs, L2CR[14–15] = 00 is recommended. For pipelined late write synchronous BurstRAMs, L2CR[14–15]
= 10 is recommended.
