Fast Assertion

30 ns min.

In FAST SCSI data transfer mode, minimum

Period

pulse width of an ACK signal sent by INIT and

an REQ signal sent by TARG for synchronous

data transfer.

19

Fast Cable Skew

5 ns max.

In FAST SCSI data transfer mode, maximum

Delay

allowable difference in transmission time over

the interface cable between any two bus signals

from any two SCSI devices.

20

Fast Deskew

20 ns min.

In FAST SCSI data transfer mode, time for

Delay

compensation for skew involved in bus signal

transmission.

21

Fast Hold Time

10 ns min.

In FAST SCSI data transfer mode, the minimum

time during which the transfer data on the

DATA BUS from the leading edge of the REQ

or ACK signal pulse must be maintained to

compensate for the hold time in the SCSI device

receiving data.

22

Fast Negation

30 ns min.

In FAST SCSI data transfer mode, the minimum

Period

time from the trailing edge of an REQ signal to

the leading edge of the next REQ signal, or from

the trailing edge of an ACK signal to the leading

edge of the next ACK signal.
