Memory Clocks & Buffers
SpectraLinear’s memory, PCI-X and PCI express clock buffers are designed for on-board clock expansion and distribution. They may be implemented as stand-alone buffers or as complementary to the system’s main clock generator. Typically, these devices receive a clock input and generate multiple output copies. A wide variety of options are available to address diverse design needs. They support PCI express as well as PCI-X, DDR and DDR2 memory clock distribution requirements. View product list +
