Note:  
1. All outputs are measured from the Vm of the rising edge of L2SYNC_IN to the Vm of the signal in question. The output timings are measured at the pins  
(see Figure 9).  
2. The outputs are valid for both single-ended and differential L2CLK modes. For flow-through and pipelined reg-reg synchronous burst SRAMs,  
L2CR[14:15] = 00 is recommended. For pipelined late-write synchronous burst SRAMs, L2CR[14:15] = 01 is recommended.  
3. All maximum timing specifications assume C = 20pF.

4. This measurement assumes C = 5pF.

5. Reserved for future use.  
6. Guaranteed by design and characterization, and not tested.  
7. Specifications are shown as a Function of Maximum Core Frequency (Fmax). They refer to the effective Fmax of the part after derating for application  
conditions. For example, a nominal 450 MHz part running at application conditions that derate its Fmax to 400 MHz will meet or exceed the specifica-  
tions shown for Fmax = 400 MHz.
