PCIAX-532 Teledyne Extender Board

The Teledyne / LeCroy / Catalyst PCIAX Extender Boards allow HOT SWAPPING or LIVE INSERTION of the Unit-Under-Test into PCI (CompactPCI for CPCI-64) bus. The “HOT SWAPPING” feature of these extenders eliminates the need for turning the PC Off and On and repeated rebooting. This feature speeds up rework, characterization, and test of Unit-Under-Test in the development phase, as well as production test. The elimination of the repeated power cycling also helps prolong the system life and the hard disc operation. These Active Extenders use a new CMOS technology (known as “Quick Switch”) for switching the signals On and Off. These switches feature a very low propagation delay, typically about 250 picoseconds, resulting in no timing degradation between the bus and the Unit-Under-Test. The switches are also bidirectional allowing the entire address range to be supported for both target and master type operation.

These Active Extender boards isolate all signals and voltages to the Unit-Under-Test, when the On-Off switch is in the Off position. All voltages are ramped down and ramped up during the power down and power up in order to eliminate any spikes. During the power down the signals to the bus become isolated as soon as the main supply, +5V, falls to +3.0V. During the power up the signals stay isolated until the main voltage is at least +3.0V.

CPCI-64 and PCIAX Rev B and higher extender boards also allow voltage margin testing of the UUT, by allowing external power supplies to replace the system power supplies as inputs to the Unit-Under-Test.
