the UCC5687, Pin 47 is DISCNCT1 and Pin 48 is DISCNCT2.
description
The UCC5686 is a twenty-seven line active terminator for low-voltage-differential (LVD) SCSI networks. This
LVD SCSI-only design allows the user to reach peak bus performance, while reducing system cost. The device
is designed as an active Y-terminator to improve the frequency response of the LVD SCSI Bus. Designed with
a 2-pF (typical) channel capacitance, the UCC5686 allows for minimal bus loading for a maximum number of
peripherals. With the UCC5686, the designer is able to comply with the Ultra2, Ultra3, Ultra160, and Ultra320
SCSI specifications. The UCC5686 also provides a much-needed system migration path for the ever improving
SCSI system standards.
This device is available in the 64-pin low-profile QFP package for ease of layout use.
Single-ended (SE) and high-voltage differential (HVD) SCSI drivers are not supported.
