JESD204B IP Core and DAC Configurations

The JESD204B IP Core parameters (L, M, and F) in this hardware checkout are natively supported by the AD9371 device's configuration registers. The transceiver data rate, sampling clock frequency, and other JESD204B parameters comply with the AD9371 operating conditions.

The hardware checkout testing implements the JESD204B IP Core with the following parameter configuration.

4 The device clock is used to clock the transceiver.
5 The frame clock and link clock are derived from the device clock using an internal PLL.
6 Sine wave pattern is used in TX_TL.1 and TX_SCR.1 test cases to verify that pattern generated in the FPGA transport layer is transmitted by DAC analog channel.
7 Single pulse and sinc patterns are used in deterministic latency measurement test cases DL.3 and DL.4 only.
