Use the TSW3100 GUI to generate and load a test pattern, either a tone, multi-tones, or modulated
waveforms. This input is required to provide the DCLK to the DAC5682z.
It is possible to configure the TSW3070EVM to use an external VCXO for application flexibility. J13 and
J14 can be used in position 2-3 to select an external VCXO or clock signal.
The board is by default set up to output signals through the OPA695 and THS3091/5. These devices can
be individually bypassed to a transformer output, if needed. To bypass the OPA695, move R6 to R109,
and R15 to R134. To bypass the THS3091/5, move R20 to R135, and R27 to R136.
