The MAX4889B/MAX4889C are ultra-high-speed, 1:2 or 2:1 PCIe® 2.0 passive switches.
These devices improve the performance of graphics applications by splitting a 16-lane PCIe bus into two 8-lane data buses.
The MAX4889B/MAX4889C feature ultra-low on-capacitance and superior return loss, enabling them to support data rates of greater than 5Gbps.
The MAX4889B/MAX4889C are ideal for desktop and notebook PCs, as well as servers.
SUNNYVALE, CA—September 11, 2008—Maxim Integrated Products (PINK OTC MARKETS: MXIM) introduces the MAX4889B/MAX4889C ultra-high-speed, 1:2 or 2:1 PCI Express® (PCIe) passive switches. These quad double-pole/double-throw (DPDT) switches are ideal for switching four half lanes of PCIe data between two destinations. To maximize performance, four devices can be used to convert 16 PCIe lanes into two sets of 8 lanes for use with either SLI™ or CrossFire™ graphics cards. Maintaining a high level of signal integrity, these switches feature very-low on-capacitance and superior return loss. The MAX4889B/MAX4889C are designed for PCIe 2.0 data switching: they offer low power consumption, support data rates greater than 5.0Gbps, and feature a flow-through pin configuration for optimized PCB layout. The MAX4889C, due to its internal biasing resistors, also supports SAS I, SAS II, and SAS 6.0Gbps data rates. The MAX4889B/MAX4889C are well suited for extreme graphics applications in desktop and notebook PCs, as well as servers.
The MAX4889B/MAX4889C operate from a single 3.3V supply, and are fully specified over the -40°C to +85°C extended temperature range. They are available in an industry-standard, 3.5mm x 9mm, 42-pin TQFN package. Prices start at $1.50 (1000-up, FOB USA).
