NOTES:
1. tSKEW2 is the minimum time between a rising CLKA edge and a rising CLKB edge for
AF to transition HIGH in the next CLKA cycle. If the time between the rising CLKB edge
and rising CLKA edge is less than tSKEW2, then
AF may transition HIGH one CLKA cycle later than shown.
2. Depth is 512 for the IDT723631, 1,024 for the IDT723641, and 2,048 for the IDT723651.
3. FIFO write (
CSA = LOW, W/RA = HIGH, MBA = LOW), FIFO read (CSB = LOW, W/RB = HIGH, MBB = LOW).

AF when FIFO is Almost-Full

AE Maximum Latency When Retransmit Increases the Number of Stored Words Above X.
NOTE:
1. X is the value loaded in the Almost-Empty flag Offset register.

NOTE:
1. CSB = LOW, W/RB = HIGH, MBB = LOW. No input enables other than RTM and RFM are needed to control retransmit mode or begin a retransmit. Other enables are shown
only to relate retransmit operations to the FIFO output register.
