DESCRIPTION
The UCC5672 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-3). 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 automatic mode select/change feature switches the terminator between
Single Ended or LVD SCSI Termination, depending on the bus
mode. If the bus is in High Voltage Differential Mode, the terminator lines
transition into a High Impedance state.
The UCC5672 is SPI-4, SPI-3, SPI-2, and SCSI-2 compliant. This device
is offered in a 28 pin TSSOP package to minimize the footprint. The
UCC5672 is also available in a 36 pin MWP package.
