Switches Enable PCIe 2.0 Switching While Offering Zero Delay

April 7, 2008 11:26 am | Product Releases | Comments

Enabling switching PCIe 2.0 data rates at 5.0Gbps and operating at 1.8V, 2.5V, or 3.3V, the MAX4888A and MAX4889A dual, passive PCIe switches allow multiple PCIe graphics cards to be used in PCs and servers. The MAX4888A (dual single-pole/double-throw- 2 × SPDT) is suited for switching two Rx or Tx equivalent lanes while the MAX4889A quad switch offers twice the capacity, handling four equivalent lanes of PCIe data with the equivalent half lanes used as one source and two destinations or two sources and one destination to minimize the effects of crosstalk. Both feature a single digital-control input (SEL) to switch signal paths designed to minimize power and skew and offer a zero delay switch. Specifications include operation from a single +3.0V to +3.6V power supply and down to +1.65V over the extended -40°C to +85°C temperature range.

Ceramic Trimmer Capacitors Designed for Minimal Capacitance Drift

April 3, 2008 8:36 am | Product Releases | Comments

Suited for telecom and microwave projects requiring miniature components, the SGC3S series ceramic trimmer capacitors measure 0.126” (3.2 mm) × 0.177” (4.50 mm) × 0.059” (1.5 mm). The capacitors are constructed with high temperature liquid-crystal polymer housings for superior durability and low dielectric loss to resist penetration by dust and flux, and are colored to make each of the five available capacitance ranges easily identifiable. Requiring minimal capacitance drift over the operating temperature range of -25°C to 85° C, the SGC3S series capacitance ranges are: SGC3S030 (Black): 1.2 pF to 3.0 pF; SGC3S060 (Blue): 2.2 pF to 6.0 pF; SGC3S100 (Ivory): 3.0 pF to 10.0 pF; SGC3S200 (Pink): 5.5 pF to 20.0 pF; SGC3S300 (Green): 8.0 pF to 30.0 pF. Designed for reflow soldering and available in embossed carriers, 1,000 pieces per 7 in (18 cm) reels, the capacitors are well-suited for placement on boards with automated pick-and-place equipment.
