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.

Data Pattern
  • PRBS-7
  • Sine 6
  • Single Pulse 7
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 The sinewave pattern is used in TL.2 and SCR.2 test cases to verify that the pattern generated in the FPGA transport layer is transmitted by the DAC analog channel.
7 The single pulse pattern is used in deterministic latency measurement test cases DL.1 and DL.2 only.
