1.5. JESD204B IP Core and ADC Configurations
The JESD204B IP core parameters (L, M and F) in this hardware checkout are natively supported by the AD9680 device's quick configuration register at address 0x570. The transceiver data rate, sampling clock frequency, and other JESD204B IP core parameters comply with the AD9680 operating conditions.
The hardware checkout testing implements the JESD204B IP core with the following parameter configuration.
