IC 9-LINE 3-5V MULTIMODE TERMINATOR FOR SCSI THROUGH ULTRA3 SCS
The UCC5630 Multi-Mode Low Voltage Differential and Single Ended Terminator
is both a single ended terminator and a low voltage differential terminator
for the transition to the next generation SCSI Parallel Interface
(SPI-2). The low voltage differential is a requirement for the higher speeds
at a reasonable cost and is the only way to have adequate skew budgets.
The transceivers can be incorporated into the controller, unlike SCSI high
power differential (EIA485) which requires external transceivers. Low Voltage
differential is specified for Fast-40 and Fast-80, but has the potential of
speeds up to Fast-320. The UCC5630 is SPI-2, SPI and Fast-20 compliant.
Consult SSOP-36 and LQFP-48 Package Diagram for exact dimensions.
The UCC5630 can not be used with SCSI high voltage differential (HVD)
EIA485. It will shut down when it sees high power differential to protect the
bus. The pinning for high power differential is not the same as LVD or single
ended and the bias voltage, current and power are also different for

Ended or Low Voltage Differential
