3.3  Optional Dynamic Signal Demonstration

Note: 

Logic inputs should NOT exceed the respective VDD.

 

For an example, see the figure below.

• Remove all shunts.
• Setup signal generator and oscilloscope.

• Generate 0 V to VDD1 peak, square wave (up to 300 MHz, but within the oscilloscope’s capabilities) on the signal generator.
• Split the signal generator output to two separate BNC cables via the splitter.
• Attach one BNC cable end to oscilloscope Channel 1 and configure the channel for 1x gain.
• Attach the 10x oscilloscope probe to oscilloscope channel 2 configure the channel for 10x gain.
• Connect the remaining BNC cable end to the BNC-to-test-clip adapter.
• Clip the signal generator’s output to A2 relative to GND1 (via either TP5 or TP3).
• Clip the oscilloscope probe’s signal line on B1 and reference to GND2 (via either TP4 or TP6).

• Observe Channel 1 (input – A2) and Channel 2 (output – B2) on the oscilloscope for various parametrics such as skew and jitter.
