1.4. JESD204B Intel® FPGA IP and ADC Configurations
The JESD204B Intel® FPGA IP core parameters of the converter AD9213 need to be configured in the registers at address 0x520 to 0x525. The transceiver data rate, sampling clock frequency, and other JESD204B parameters comply with the AD9213 operating modes.
The hardware checkout testing implements the JESD204B Intel® FPGA IP core with the following parameter configuration.
Global setting for all configuration:
- CS = 0
- CF = 0
- Subclass = 1
- FPGA Management Clock (MHz) = 100
- PCS Option = Soft PCS
