DESCRIPTION
The SiP5630 provides active bus termination suitable for all
SCSI bus operational modes from SCSI-1 through SPI-4
(Ultra 320). The termination includes impedance matching of
the SCSI bus to minimize signal reflections from the end of the
bus, as well as required SCSI bus biasing for either S/E (Single
Ended) or LVD (Low Voltage Differential) operation.
The SiP5630 senses the operational state of the SCSI bus via
the DIFFSENS bus signal, and automatically switches to S/E
or LVD operation as required. It cannot be used on an HPD
(High Power Differential) SCSI bus, and goes into high
impedance mode when the voltage on the DIFFSENS line
indicates HPD operation. The SiP5630 also presents high
impedance to the SCSI bus if the DISABLE pin is asserted, or
if TERMPWR is removed from the IC.
The SiP5630 has nine (9) output channels (T1-T9). Each
output channel provides termination for one SCSI data signal,
parity signal or control signal. Two SiP5630 ICs provide
complete termination for a narrow SCSI Bus; three ICs provide
complete termination for a wide SCSI bus.
The SiP5630 is available in a lead (Pb)-free QSOP-36
package for operation over the temperature range of 0 to
70
_C.
