XCG Clock Generator
The XCG Clock Generator provides the necessary clock signals to support an XDR memory system. It is an off-the-shelf solution provided by several leading IC companies for a broad range of high performance clocking applications. Guaranteed to provide clocks that meet specifications for both the XIO Cell and the XDR DRAM device, the XCG provides four programmable differential outputs using a reference input clock of 100MHz or 133MHz. The XCG also supports spread spectrum modulation, reducing the EMI generated from the clock distribution network.
