2.3 Required Equipment
• The following equipment is included in the EVM evaluation kit:
– ADC368xEVM Evaluation board (EVM)
– LVDS FPGA Interposer Card
– Mini-USB cable
The following equipment is
not
included in the EVM evaluation kit, but is required for evaluation of this EVM:
• TSW1400EVM data capture board and related items
•
software
• PC running Microsoft
®
Windows
®
7, or 10
• One low-noise signal generator for the analog input (If using onboard clock option, no additiona signal
generators are required).
• Two low-noise signal generators for the sample clock and DCLKIN. (These two signal generators must share
the same reference frequency).
TI recommends the following generators:
• Rohde & Schwarz SMA100A
• Rohde & Schwarz SMA100B
A bandpass filter is required for the analog input signal due to most signal generators addition of phase noise or
spurious components. A bandpass filter should also be used for the sample clock input. The DCLKIN input does
not require a bandpass filter. If bandpass filters are not used, then the true performance of the ADC may not be
seen clearly, and will be limited by the performance of the signal generators being used.
The following recommended bandpass filter will have:
• Bandpass filter, greater than or equal to 60-dB harmonic attenuation, less than or equal to 5% bandwidth,
greater than 18-dBm power, less than 5-dB insertion loss
• Signal-path cables, SMA
