Technobox Adapter Converts Either PCI or PCI-X Board to a PMC Site

This latest PCI-to-PMC adapter from Technobox is a successor to the company's 1505 PCI-to-PMC adapter. The 4044 features two PCI connectors — one for a 32-bit 5 Volt PCI card, the other for either a 32-bit or 64-bit 3.3 Volt board. Support for the new PCI-X Capable signal provides for the use of either legacy style PCI boards (33 or 66 MHz, 5V or 3.3V) or the newer PCI-X boards (up to 110 MHz, 3.3v).

Variations of the 4044 are offered which include a 10-watt, 5-to-3.3 Volt DC-to-DC converter for those systems that do not provide 3.3 Volt power, a PLL clock buffer optimizing setup and hold times on the PCI-X bus allowing the skewing of the front edge of the PCI clock by +/- 4 ns (in 1 ns steps), as determined by a rotary switch setting.

To assure optimal performance with high-speed PCI-X boards, the adapter was carefully designed with such features as an eight-layer PCB and the use of Schottky diodes to minimize signal undershoot and other transmission line effects. LEDs indicate the status of power and key bus signals. A second set of LEDs is dedicated to showing PCI-X bus cycles as they are decomposed by the 4044 into MEMORY RD/WR, I/O RD/WR and CONFIGURATION RD/WR. Six 20-pin connectors are available for attachment of Agilent (HP) logic analyzer termination adapters. Additionally, a special voltage level signal that is proportional to the actual bandwidth utilization provides a measurement of board performance.

The 4044 lists for $595.00. Quantity discounts are available. The adapter is available for immediate shipment.
