• Your choice of:
  • 3.3V or 5V to 5V signal conversion.
  • 3.3V or 5V to 3.3V signal conversion.
• Ability to run secondary bus at half the primary bus frequency. Multiple boards may be used in series to achieve lower frequencies.
• Active PCI extender with three 32/64-bit slots.
• 32 to 64 bit write combining.
• PCI frequencies up to 66 MHz.
• Works with 3.3V or 5V and 32 bit or 64 bit host PCI bus. Universal connector plugs into 3.3V or 5V PCI busses.
• Fully PCI 2.1 compliant.
• Intel® 21154 PCI-to-PCI bridge.
• Onboard +3.3V regulator delivers up to 10A local power to secondary PCI slots (+3.3V not required on backplane!).
• Up to 5A of +3.3V may be driven onto backplane. Resettable fuse provides overload protection.
• LED's clearly show system status, including primary and secondary PCI I/O voltages, power supply, and bus activity.
• Clearly labeled test posts for all PCI signals.

PCI Extender
$595

The DNPCIEXT-S3/5 is an extender card designed to aid in the debug and test of PCI-based circuit boards. This is an active extender card; an Intel® 21154 PCI to PCI bridge is used to isolate the primary PCI bus from the three secondary PCI bus slots. Since primary and secondary busses are electrically isolated, a much cleaner electrical signaling environment exists, and a single host slot can be expanded to contain up to three plug-in PCI cards. The primary PCI frequency can range from 0 to 66.66 MHz. The secondary PCI frequency is configurable to be the primary frequency or one half the primary frequency. DIP switches are provided to force the primary or secondary busses to 33MHz.

This extender is available in two versions to cover all your voltage-conversion needs:

 

Primary I/O	Secondary I/O	Model
+3.3V	+3.3V	DNPCIEXT-S3
+5V	+3.3V	DNPCIEXT-S3
+3.3V	+5V	DNPCIEXT-S5(no longer avail)
+5V	+5V	DNPCIEXT-S5(no longer avail)
