Technobox Part Number 4978
SAS / SATA Controller PMC
with SFF-8470 Connectors
(RoHS Compliant Lead-free)
The Technobox 4978 Dual Port SAS/SATA controller PMC is
based on the LSI Logic 1068 controller and provides 8 lanes of either SAS or SATA connectivity at 3.0 Gb/s per lane.
Two SFF-8470 connectors at the PMC front panel are used for connectivity. Each connector supplies 4 lanes. A jack-screw style retaining
method is used to allow operation in rugged environments.
The design features a 64Kb serial EEPROM which is used to store user-configurable parameters by the LSI BIOS. A 2Mx8b FLASH memory
holds the BIOS for Intel-platforms and the BIOS is burned in the FLASH as delivered. A 32Kx8b Non-Volatile RAM holds mirroring data as required
by the LSI logic firmware.
is provide for the LSISAS1068 controller. A switching regulator is used to provide 1.2V core power for the LSI chip from the 3.3V power rail for
optimum power effi ciency. Only 3.3V power from the host is required. General Purpose (GPIO) signals, link Fault and activity signals, an I2C
bus, and TX/RX data for a UART are presented at the PN4 Rear I/O connector of the PMC for applications requiring these functions.
