The Pulse Instruments PI-41400 Dual Channel Clock Driver Card, along with other stimulus cards, is designed for the modular instrument platform CompactPCI.  This card is a 6U Eurocard size that will plug directly into the CompactPCI  chassis. As a test or design engineer you must have state-of-the-art tools to test, characterize and verify your complex semiconductor devices and circuit boards. The PI-41400 Dual Channel Clock Driver Card is one of the high performance, low-cost test instrumentation tools being developed by Pulse Instruments.

Instrument Description

The PI-41400 is a dual channel Clock Driver card capable of operating up to 190 MHz into a 50-ohm load and up to 80 MHz at an amplitude of 8 volts into a 1-megohm load. Into a high impedance load the output voltage range is from a –3 volts to 8 volts with the output pulse amplitude ranging from 0.5 V to 9 V. When driving a 50 load the voltage range is –1.5 volts to 4.5 volts with the output pulse amplitude ranging from 0.25 V to 4.5 V. The rise and fall times of the output pulse are variable from 1.2 ns to 9 ns into a 50-ohm load and <5 ns to 9 ns into a HiZ load. The output pulse amplitude and the load being driven determine the range of variability. The driver output can be set for tri-state operation and the output polarity can be set for ‘Normal’ or ‘Inverted’ operation through software.

The input drive signal, software selected, can be either TTL or single-ended ECL. There is also an ‘Opto Input’ SMA connector so the driver can be isolated from the input drive signal. Using the Opto Input for the stimulus signal limits the operating frequency to 30 MHz. For further noise immunity the PI-41400 has a separate connector that will allow the use of external laboratory type power supplies to power the critical circuitry on the board. Additionally there are banana jacks on the front panel to provide voltage and current sense measurements.

There are two monitoring features for the output signals. The first is a separate SMA connector for each channel that provides the same output signal as the main output.  The second monitoring feature is an LED that gives an indication between active operation or tri-state mode operation.
