PI-41401 100 MHz Clock Driver


The Pulse Instruments PI-41401 Four 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 need state-of-the-art tools to test, characterize and verify your complex semiconductor devices and circuit boards.  The PI-41401 Four Channel Clock Driver Card is one of these high performance, low-cost test instrumentation tools developed by Pulse Instruments.

Instrument Description

The PI-41401 is a four channel Clock Driver card capable of operating up to 140 MHz at 3V and 100 MHz at 5V amplitudes into a 50 Ohm load.   The PI-41401 has a clock rate of  90 MHz at an amplitude of 5 volts into a 1-MOhm load.  Into a high impedance load the output voltage range is from –5 volts to +8 volts with the pulse amplitude ranging from 0V to 9V.  When driving a 50 load the voltage range is –2.5 volts to 4.0 volts with the pulse amplitude ranging from effectively 0V to 4.5V.  Each channel has a common edgespeed control to vary the rising and falling edges of the output waveform.  The adjustable slew rate range, for any amplitude, is the minimum edgespeed of that amplitude times 5.  The output pulse amplitude and the load being driven determine the range of variability. 

Unlike most other drivers, the PI-41401 can have the Hi and Low levels programmed for the same value. This is useful when measuring the input current to a DUT pin.  Each of the driver channels can be set for tri-state operation via software control.  To minimize waveform distortion caused by reflections from impedance mismatches, each channel output is back-matched with an equivalent 50-ohm termination resistor.

A TTL signal is used to drive the input of the PI-41401 Clock Driver.  The terminating resistor for this input can be selected under software control to be either 50-ohms or 1Kohm.  For added noise immunity, the PI-41401 has a separate connector that will allow the use of external laboratory type power supplies to power the critical circuitry on the board.   The unit has the capability of making voltage and current sense measurements using one of two methods, either by connecting a DVM to the output sense terminals or via the internal 8-bit DAC.  The output sense terminals are banana jacks on the front panel.
