3 Quick Start Procedure for Bypass Mode

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

  1. Connect the ADC32RF5xEVM to the TSW14J58EVM using the FMC connectors.
  2. Connect a 6V, 5A minimum power supply to connector J2.
  3. Connect a USB 2.0 TypeA to Mini-B cable to connector J23.
  4. Connect a USB 3.0 TypeA to Micro-B cable to connector J1.
  5. Turn on the power supply and toggle the power switch (SW5) to the "ON" position. The fan should start spinning and the current draw should settle around 2.1 A.

ADC32RF5xEVM

  1. Connect a 12 V , 2 A minimum power supply to the connector J11.
  2. Connect a USB 2.0 TypeA to Mini-B cable to connector J12.
  3. Connect a filtered 2.56 GHz clock signal (+10 dBm) to input J1 (EXTCLK), then enable the signal generator output.
  4. Connect a filtered 300 MHz input signal (+10 dBm) to input J3 (INA1), then enable the signal generator output.

GUI Setup

  1. 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.
  2. 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.
  3. Enter 2.56 G into the ADC Output Data Rate field. A message will appear stating "New lane rate is 12.8G due to ADC Output Data Rate change". When this appears, press OK.
  4. Enter 300 M into the ADC Input Target Frequency field and tick the checkbox "Auto Calculation of Coherent Frequencies". You will notice that the 300M changes to 300.039 M.
  5. Open the ADC32RF5x GUI. Verify that the green USB Status indicator is illuminated as shown in Figure 3-1 below. If the indicator is red (simulation mode), verify that the USB cable is connected and that the ADC32RF5xEVM is powered on and press the Reconnect USB button.
