Maxim Integrated Products 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.

Vishay Intertechnology Inc. announced a new low-cost, long-life panel potentiometer with a low temperature coefficient down to ±150 ppm/°C and small 9.6-mm size. While standard low-cost panel potentiometers reach 50,000 cycles, the P10L offers a long life of 500,000 cycles. For designers, this reduces the need for replacement parts, increasing reliability and lowering maintenance costs.
