SS8218
Ultra160 Multi-mode LVD/SE SCSI Terminator
Features
Auto-selectable multi-mode Single-Ended
General Description
The SS8218 Multi-mode LVD/SE SCSI terminator provides a smooth transition to the next generation of the SCSI Parallel Interface (SPI-3). It automatically senses the bus, via DIFFSENS, and switches the termination to either single-ended (SE) or low voltage differential (LVD) SCSI, dependent on which type of devices are connected to the bus. If the SS8218 detects a HVD SCSI device, it switches to a high impedance state. For a 16-bit Wide SCSI bus to be operational, three SS8218 terminators are needed. The Multi-mode terminator contains all functions required to terminate and auto detect and switch modes for SCSI Parallel Interface (SPI) bus architectures.
