IDT723626/723636/723646 CMOS TRIPLE BUS SyncFIFO
WITH BUS-MATCHING 256 x 36 x 2, 512 x 36 x 2 and 1,024 x 36 x 2
NOTES:
1. t
SKEW2
is the mnimumtime between a rising CLKC edge and a rising CLKA edge for
AFC
to transition HIGH in the next CLKC cycle. If the time between the rising CLKC edge
and rising CLKA edge is less than t
SKEW2
, then
AFC
may transition HIGH one CLKC cycle later than shown.
2. FIFO2 write (MBC = LOW), FIFO2 read (
CSA
= LOW, W/
R
A = LOW, MBA = LOW). Data in the FIFO2 output register has been read fromthe FIFO.
3. D = MaximumFIFO Depth = 256 for the IDT723626, 512 for the IDT723636, 1,024 for the IDT723646.
4. Port C size is word or byte,
AFC
is set LOW by the last word or byte write of the long word, respectively.

AFC
when FIFO2 is Almost-Full (IDT Standard and FWFT Modes)
Figure 25. Timing for
AEA
when FIFO2 is Almost-Empty (IDT Standard and FWFT Modes)
Figure 26. Timing for
AFA
when FIFO1 is Almost-Full (IDT Standard and FWFT Modes)
NOTES:
1. t
SKEW2
is the mnimumtime between a rising CLKC edge and a rising CLKA edge for
AEA
to transition HIGH in the next CLKA cycle. If the time between the rising CLKC edge
and rising CLKA edge is less than t
SKEW2
, then
AEA
may transition HIGH one CLKA cycle later than shown.
2. FIFO2 Write (MBC = LOW), FIFO2 read (
CSA
= LOW, W/
R
A = LOW, MBA = LOW). Data in the FIFO2 output register has been read fromthe FIFO.
3. If Port C size is word or byte, t
SKEW2
is referenced to the rising CLKC edge that writes the last word or byte of the long word, respectively.
NOTES:
1. t
SKEW2
is the mnimumtime between a rising CLKA edge and a rising CLKB edge for
AFA
to transition HIGH in the next CLKA cycle. If the time between the rising CLKA edge
and rising CLKB edge is less than t
SKEW2
, then
AFA
may transition HIGH one CLKA cycle later than shown.
2. FIFO1 Write (
CSA
= LOW, W/
R
A = HIGH, MBA = LOW), FIFO1 read (
CSB
= LOW, MBB = LOW). Data in the FIFO1 output register has been read fromthe FIFO.
3. D = MaximumFIFO Depth = 256 for the IDT723626, 512 for the IDT723636, 1,024 for the IDT723646.
4. If Port B size is word or byte, t
SKEW2
is referenced fromthe rising CLKB edge that reads the last word or byte of the long word, respectively.
