IDT72V2101/72V2111 3.3V HIGH DENSITY CMOS
SUPERSYNC FIFO
TM
262,144 x 9, 524,288 x 9
NOTES:
1. Retransmit setup is complete after OR returns LOW.
2. No more than D - 2 words may be written to the FIFO between Reset (Master or Partial) and Retransmit setup. Therefore, IR will be LOW throughout the Retransmit setup
procedure. D = 262,145 for the IDT72V2101 and 524,289 for the IDT72V2111.
3. OE = LOW
4. W1, W2, W3 = first, second and third words written to the FIFO after Master Reset.
5. There must be at least two words written to the FIFO before a Retransmit operation can be invoked.

NOTE:
1. X = 17 for the IDT72V2101 and X = 18 for the IDT72V2111.

NOTES:
1. m = PAF offset .
2. D = maximum FIFO depth.
In IDT Standard mode: D = 262,144 for the IDT72V2101 and 524,288 for the IDT72V2111.
In FWFT mode: D = 262,145 for the IDT72V2101 and 524,289 for the IDT72V2111.
3.
t
SKEW2
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 t
PAF
). If the time between the rising edge of
RCLK and the rising edge of WCLK is less than t
SKEW2
, 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.

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.
