Almost all users of oscillators have suffered from one delivery issue or another. This is primarily because the process of manufacturing a crystal is based on mechanical cutting and plating techniques. Due to the many complexities, an XO/VCXO lot may take 10 to 15 weeks to build. Before the manufacturing process begins, the crystal frequency must be known. This long process that requires customization of the frequency at the very beginning makes stocking cost prohibitive in most situations. On the other hand, Skyworks Solutions keeps pre-compensated and pre-tested stock on hand. When an order comes in, the appropriate stock is pulled out and programmed to the exact frequency. This simple step takes no longer than two weeks for samples and four weeks for production quantities.
