1.4. JESD204B Intel® FPGA IP and ADC Configurations

The JESD204B Intel® FPGA IP core parameters in this hardware checkout are natively supported by the AD9208 device. The transceiver data rate, sampling clock frequency, and other JESD204B parameters comply with the AD9208 operating conditions.

The hardware checkout testing implements the JESD204B Intel® FPGA IP core with the following parameter configuration.

Global setting for all configuration:

  • N’ = 16
  • CS = 0
  • CF = 0
  • Subclass = 1
  • FPGA Management Clock (MHz) = 100
  • Character Replacement = Enabled
  • PCS option = Soft PCS

3 The FPGA transceiver reference clock is used to clock the transceiver.
4 The core reference clock from Si5341 with frequency of the FPGA transceiver reference clock is used to derive frame clock and link clock frequencies.
