Bypass mode is the default operating
mode for the ADC32RF5x device family. When operating in this mode, the digital
decimation filters that the ADC32RF5x offers is bypassed. Additionally, the user has
the option to enable averaging of each internal pair of ADCs per individual channel.
Operating in bypass mode without averaging provides the lowest power consumption for
ADC32RF5x devices.
TSW14J58EVM
- Connect the TRF1305-ADC32RFEVM to
the TSW14J58EVM using the FMC connectors.
- Connect a 6V, 5A minimum power
supply to connector J2.
- Connect a USB 2.0 Type-A to
Mini-B cable to connector J23.
- Connect a USB 3.0 Type-A to
micro-B cable to connector J1.
- Turn on the power supply and
toggle the power switch (SW5) to the ON position. The fan starts spinning
and the current draw settles at approximately 2.1A.
TRF1305-ADC32RFEVM
- Connect a 12V, 2A minimum power
supply to the connector J11.
- Connect a USB 2.0 Type-A to
mini-B cable to connector J12.
- Make sure jumper settings are as
detailed in Table 3-1.
- Connect a filtered 2.56GHz clock
signal (+10 dBm) to input J1 (EXTCLK), then enable the signal generator
output.
- Connect a filtered 300MHz input
signal (-20 dBm) to input J8 (INA), then enable the signal generator
output.
GUI Setup
- Open High Speed Data Converter
Pro (HSDC Pro) and select the TSW14J58. If no device is found, verify that power
is on and both USB cables are connected.
- Select the device firmware
labeled ADC32RF5x_8224_12G-16G and update the firmware by pressing
Yes on the pop-up window and waiting for the Downloading
Firmware message to finish.
- Enter 2.56 G into the ADC
Output Data Rate field. A message appears stating New lane rate is 12.8G due
to ADC Output Data Rate change. When this appears, press OK.
- Enter 300M into the ADC
Input Target Frequency field and tick the checkbox Auto Calculation of
Coherent Frequencies. Notice that the 300M changes to 300.039M.
- Open the ADC32RF5x GUI. Verify
that the green USB Status indicator is illuminated as shown in Figure 3-3. If the
indicator is red (simulation mode), then verify that the USB cable is connected
and that the TRF1305-ADC32RFEVM is powered on and press the Reconnect USB
button.
