Spectra-Strip's new Fast 20/40 SCSI cable is designed to comply with the
recently released ANSI standard for Fast 20 SCSI devices operating at
20 MB data rates. Two versions of the cable are offered: 50 conductor
26 AWG on .050" centers PVC for 8 bit narrow
applications (see part number 191-2601-150),and 68 conductor 30 AWG
on .025" centers for 16 and 32 bit wide applications (part number 193-3099-988).
With the new cable, characteristic impedance is higher (and tighter)
at 90 + 6 ohms and signal-to-signal
skew is controlled to within .025 ns/ft max, to accommodate the higher frequency
Fast 20 signals.
