G219 Ultra320 Multi-mode LVD/SE SCSI Terminator Features „Auto-selectable multi-mode Single-Ended General Description The G219 Multi-mode LVD/SE SCSI terminator provides a smooth transition into the next generation of the SCSI Parallel Interface (SPI-4).
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 G219 detects a HVD SCSI device, it switches to a high impedance state.
For a 16-bit Wide SCSI bus to be operational, three G219 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.
For the SE termination, one regulator and nine precision 110ohm resistors are used.
For the LVD termination, the G219 integrates 18 regulated supplies with nine precision resistor strings.
