NOTES:
1. For IDT Standard mode: D = maximum FIFO depth. D = 16,384 for the IDT72V261LA and 32,768 for the IDT72V271LA.
2. For FWFT mode: D = maximum FIFO depth. D = 16,385 for the IDT72V261LA and 32,769 for the IDT72V271LA.
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 tPAE). 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.
NOTES:
1. m =
PAF offset.
2. D = maximum FIFO depth.
In IDT Standard mode: D = 16,384 for the IDT72V261LA and 32,768 for the IDT72V271LA.
In FWFT mode: D = 16,385 for the IDT72V261LA and 32,769 for the IDT72V271LA.
3. tSKEW2 is the minimum time between a rising RCLK edge and a rising WCLK edge to guarantee that
PAF will go HIGH (after one WCLK cycle plus tPAF). If the time between
the rising edge of RCLK and the rising edge of WCLK is less than tSKEW2, then the
PAF deassertion time may be delayed one extra WCLK cycle.
4.
PAF is asserted and updated on the rising edge of WCLK only.
