While the xSil267 controls serial-only, multi-slot applications such as those where Secure Digital (SD), Multimedia Card (MMC), and Memory Stick (MS) media interface with a PC Express Card adapter or USB Host, the xSil268 controls both serial and parallel interfaces
for multi-slot applications enabling it to read from a wide range of media formats including UDMA CompactFlash (CF), MMC 4.
Because of the inherent physical limitations of parallel interfaces
, inexpensive or cost-effective serial interfaces like 10- and 40-Gigabit Ethernet, SATA and 3GIO (PCI Express) are poised to be part of this flourishing future for IP storage.
The devices are designed to protect and filter high-speed parallel interfaces
that operate at speeds up to 60Mbs without signal degradation.
For high bandwidth switch fabrics, these parallel interfaces
cannot run across the backplane due to signal density limitations.
0 ports, two PS/2 ports, one intergrated SmartCard reader and two serial and one parallel interfaces
are included with the standard equipment.
Computer parallel interfaces
and serial interfaces such as RS232/485/422, SPI (serial peripheral interface), and Inter-Integrated Circuit (I2C) bus
