Jumper List - Texas Instruments ADS5400EVM-CVAL User Manual

Overview
2. Connect the 5-V supply between J5 and J6 (GND), If you are using the TSW1200 for capture, it can
also be used to source 5 V for the EVM. On the TSW1200, configure JP8 to short 1-2 and J22 to short
1-2 and jumper over 5 V from the banana jacks on the TSW1200 to J5 on the ADC EVM. Do not
connect a voltage source greater than 5.5 V.
3. Switch on power supplies.
4. Using a function generator with 50-Ω output impedance, generate a 0-V offset, 1.5-Vpp sine-wave
clock into J12. The frequency of the clock must be within the specification for the device speed grade.
5. Use a frequency generator with a 50-Ω output impedance to provide a 0-V offset, –1-dBFS-amplitude
sine-wave signal into J1. This provides a transformer-coupled differential input signal to the ADC.
6. Connect the TSW1200 or suitable logic analyzer to J4 to capture the resulting digital data. If you
connect a TSW1200 to capture data, follow the additional alphabetically labeled steps. For more
information, see
(a) After installing the TSW1200 software and connecting the TSW1200 to the USB port, open the
TSW1200 software.
(b) Depending on the ADC under evaluation, select ADS5400 from the "TI ADC Selection" pulldown
menu.
(c) Change the "ADC Sample Rate" and "ADC Input Frequency" to match those of the signal
generator.
(d) After selecting a Single Tone FFT test, press the "Capture Data" button.
