The SiP5696 operates through SPI-5 (Ultra 640). 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 SiP56xx senses the operational state of the SCSI bus via the DIFFSENS bus signal, and automatically switches to S/E or LVD operation as required. The SiP56xx family 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 SiP56xx also presents high impedance to the SCSI bus if the DISABLE pin is asserted, or if TERMPWR is removed from the IC. An optional integrated mode change delay filter eliminates the need for a bulky 4.7-μF low pass filter capacitor to be compliant with SPI-3 mode change timing requirements. Devices in the SiP56xx family are available in a lead (Pb)-free package for operation over the temperature range of 0 to +70 ºC.
