Test-and-measurement vendor Agilent Technologies (Palo Alto, Calif.) now has a logic analysis probe for folks designing-in Intel Pentium 4 microprocessors in 775-land packages. Agilent's new E8045B logic analyzer probe promises to provide high visibility into the Pentium 4 system bus.
“The Pentium 4 in the 775-land package presents debug and validation challenges,” avows Ron Nersesian, VP and general manager of Agilent's Design Validation Division . “But, the new E8045B analysis probe helps you troubleshoot and optimize devices without corrupting the integrity of the processor. The E8045B analyzer interface enables the connection of logic analyzers to LGA775 processors with extremely low mechanical and electrical intrusion.”
The 775-land package probe adapter fits between the processor and its socket, so that bus loading and mechanical intrusions are minimized because the probe interface adapter is electrically passive.
The probe simplifies validation of the Pentium 4 system bus by aligning the source-synchronous, quad-pumped data lines and double-pumped address lines with the b-clk frequency control signals. As such, validation engineers don't need to consider multiple clock domains because of this simplification.
Time-Correlated To Other Products
For complete system validation, the Agilent E8045B can be time-correlated to other products from Agilent, including analysis probes for DDR 1 and DDR 2 memories, fully buffered DIMM (FBD), Infiniband, PCI, PCI Express (including advanced switching), PCI-X 1.0 and 2.0, SATA 1 and 2 , and Universal Serial Bus 1.0, 1.1 and USB 2.0 .
In addition to supporting the LGA775 processor package from Intel, Agilent also provides support for Pentium 4s in 478-pin packages, Pentium Ms in 478-pin packages, Xeons in 603-pin and 604-pin packages, and the Intel Itanium Processor in its 611-pin package.
Price and Availability
The E8045B logic analysis probes are priced beginning at $85,000 each.
