PCI Express core enables Fibre Channel ASICs
QLogic Corp has incorporated the Rambus PCI Express digital controller core in its new line of Fibre Channel storage processor ASICs.
The XCG is an off-the-shelf clock generator solution provided by several leading IC companies for a broad range of high performance clocking interface applications.
The XCG revision 1.0 is based on the collaborative work between Rambus and XCG suppliers.
Extensive in-system testing and demanding qualification efforts have led to the refinement of the XCG specification and resulted in a clock generator that is ready to support mass production of high frequency XDR systems for graphics processing, consumer electronics, and computing applications.
The XDR clock generator supports the complete XDR memory subsystem as well as the industry's fastest processor bus interface, the 400MHz to 8.0GHz Rambus FlexIO, by using a reference clock input with or without spread spectrum modulation.
Major XCG components include a phase lock loop, a bypass multiplexer and four differential output buffers.
"The latest version of the Rambus XDR clock generator represents a state-of-the-art clocking solution that meets the high performance, high bandwidth requirements of today's most demanding applications such as graphics processing and consumer electronics", said David Nguyen, Vice President of Engineering at Rambus.
"As a vital component of XDR DRAM technology, XCG supports a total memory system solution that achieves an order of magnitude higher performance than today's standard memories".
The XCG for use in systems that incorporate Rambus' XDR memory solutions is available from Cypress Semiconductor Corporation, IDT and Texas Instruments.
