6 Hardware Setup

This section provides directions and illustrations for setting up the hardware.

By default, the FMC+ interface EEPROM on the ADC12DJ3200EVM is installed. Without this part, the FMC3_VADJ voltage for the FPGA bank that drives the JESD204B SYNC will be set to 0 V, thus preventing the SYNC signal from working. Using the ADC manual SYNC is a work around for this. U5 (24C65T-I/SM from Microchip) is programmed with the provided .bin file called "FMC-ADC12DJ3200-CVAL.bin". This .bin file uses address 0x53 which is required for the FMC+ slot on the Alpha Data board and will set the FMC3_VADJ to 1.8 V after power up. With the EEPROM installed and programmed properly, after power up, test point TP3 on the Alpha Data board should be at 1.8 V.

  1. Connect the Alpha Data board with ADC12DJ3200 CVAL EVM. Use the FMC+ connector (J3) to connect the ADC EVM.
  2. Connect the output power cable from the CX 650 power supply to the Alpha Data board as Figure 6-2 shows:

  3. Connect the JTAG cable between the PC and the JTAG port on the USB daughter board.
  4. Connect a USB cable between USB daughter board and the PC, see Figure 6-3.

  5. Connect a USB cable between the ADC12DJ3200EVM (J31) and the PC. Connect the 5-V power supply that can source a minimum of 3 A to J37 on the ADC12DJ3200EVM. TP12 (+5 V) and TP13 (GND) provide another option for connecting to 5 V.
  6. Connect a RF analog input source to J2 (VINA) of the ADC12DJ3200EVM. This guide uses a 70-MHz source at 0 dBm from a TI TSW2700EVM.
  7. Turn on the Alpha Data board. The power switch is near the power input cable.
