Clock and Strobe Sources

The following tables describe the Clock and Strobe sources available for the GX5280.

Internal high-precision Programmable Clock

The GX5280 provides an Internal high-precision Programmable Clock – programmable clock from 5Hz to 200MHz with increments of 1HZ or 0.02%. See Specification for details. The 10MHz clock from the PXI backplane provides reference clock for the On-board high-precision PLL.

External Clock

supplied by the user through pin 31 on J3 Timing connector, can be from 5Hz to 200MHz. See Specification for details.

External Strobe

supplied by the user through pin 32 on J3 Timing connector, can be from 5Hz to 200MHz. See Specification for details.

 

The figure Clock Source Block Diagram shows how the  Clock and Strobe Sources are routed to produce the GX5280 clock signals.
