1.4. JESD204B IP Core and AD9144 Configurations
The JESD204B IP core parameters (L, M and F) in this hardware checkout are natively supported by the AD9144 device's configuration registers. The transceiver data rate, sampling clock frequency, and other JESD204B parameters comply with the AD9144 operating conditions.
The hardware checkout testing implements the JESD204B IP core with the following parameter configuration.
