Notes:
1. Rise and fall times for the L2SYNC_IN input are measured from 20% to 80% of L2OVDD.
2. All input specifications 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 specifications 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-
Ω load (see
4. The outputs are valid for both single-ended and differential L2CLK modes. For pipelined registered synchronous BurstRAMs,
L2CR[14–15] = 01 or 10 is recommended. For pipelined late write synchronous BurstRAMs, L2CR[14–15] = 11 is
recommended.
5. Guaranteed by design and characterization.
6. Revisions prior to Rev. 2.8 (Rev. E) were limited in performance and did not conform to this specification. For more
information, refer to Section 10.2, “Part Numbers Not Fully Addressed by This Document.”
