Standard
Timing specification
17
Transfer Period
–
In synchronous data transfer mode, the minimum
time (minimum repetition time) from the leading
edge of an REQ signal to the leading edge of the
next REQ signal or from the leading edge of an
ACK signal to the leading edge of the next ACK
signal. The actual value is defined using a
SYNCHRONOUS DATA TRANSFER REQUEST
message exchanged between the INIT and TARG.

18
Fast Assertion
Period
30 ns min.
In FAST SCSI data transfer mode, minimum pulse
width of an ACK signal sent by INIT and an REQ
signal sent by TARG for synchronous data transfer.
19
Fast Cable Skew
Delay
5 ns max.
In FAST SCSI data transfer mode, maximum
allowable difference in transmission time over the
interface cable between any two bus signals from
any two SCSI devices.
20
Fast Deskew
Delay
20 ns min.
In FAST SCSI data transfer mode, time for
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
Period
30 ns min.
In FAST SCSI data transfer mode, the minimum
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.
