1.4. JESD204B IP Core and DAC Configurations
TheJESD204B IP Core parameters (L, M and F) in this hardware checkout are natively supported by the AD9162 device's configuration registers. The transceiver data rate, sampling clock frequency, and other JESD204B parameters comply with the AD9162 operating conditions.
The hardware checkout testing implements the JESD204B IP Core with the following parameter configuration.

2 The device clock is used to clock the transceiver and IO PLL.
3 The frame clock is derived from the device clock using an IO PLL.
4 The link clock is derived from the device clock using an IO PLL.
5 Sine wave pattern is used in TL.2 and SCR.2 test cases to verify that pattern generated in the FPGA transport layer is transmitted by DAC analog channel. Single pulse pattern is used in deterministic latency measurement test cases DL.1 and DL.2 only. Constant pattern is used to check the STPL test. DAC does not support STPL test for modes with 3 and 6 lanes.
