JUNE 1, 2010
NOTES:
1. n =
PAE offset.
2. For IDT Standard mode
3. For FWFT mode.
4. tSKEW2 is the minimum time between a rising WCLK edge and a rising RCLK edge to guarantee that
PAE will go HIGH (after one RCLK cycle plus tPAES). If the time between the rising
edge of WCLK and the rising edge of RCLK is less than tSKEW2, then the
PAE deassertion may be delayed one extra RCLK cycle.
5.
PAE is asserted and updated on the rising edge of WCLK only.
6. Select this mode by setting PFM HIGH during Master Reset.

NOTES:
1. m =
PAF offset.
2. D = maximum FIFO Depth.
In IDT Standard mode: if x18 Input or x18 Output bus Width is selected, D = 131,072 for the IDT72V2103 and 262,144 for the IDT72V2113. If both x9 Input and x9 Output bus Widths
are selected, D = 262,144 for the IDT72V2103 and 524,288 for the IDT72V2113.
In FWFT mode: if x18 Input or x18 Output bus Width is selected, D = 131,073 for the IDT72V2103 and 262,145 for the DT72V2113. If both x9 Input and x9 Output bus Widths are
selected, D = 262,145 for the IDT72V2103 and 524,289 for the IDT72V2113.
3.
PAF is asserted to LOW on WCLK transition and reset to HIGH on RCLK transition.
4. Select this mode by setting PFM LOW during Master Reset.
