General Description
The G219 Multi-mode LVD/SE SCSI terminator pro-
vides a smooth transition into the next generation of
the SCSI Parallel Interface (SPI-4). It automatically
senses the bus, via DIFFSENS, and switches the ter-
mination 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 re-
quired 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.
