1.3.3. Descrambling

The PRBS/Ramp checker at the receiver transport layer checks the data integrity of descrambler.

The Signal Tap Logic Analyzer tool monitors the operation of the receiver transport layer.

Table 4.  Descrambler Test Cases
Test Case Objective Description Passing Criteria

SCR.1

 Check the functionality of the descrambler using Ramp test pattern.

Enable scrambler at the ADC and descrambler at the JESD204B receiver IP Core.

The signals that are tapped in this test case are similar to test case TL.1

  • The jesd204_rx_data_valid signal is asserted.
  • The data_error and jesd204_rx_int signals are deasserted.

SCR.2

 Check the functionality of the descrambler using PRBS-9 test pattern.

Enable scrambler at the ADC and descrambler at the JESD204B receiver IP Core.

The signals that are tapped in this test case are similar to test case TL.2

  • The jesd204_rx_data_valid signal is asserted.
  • The data_error and jesd204_rx_int signals are deasserted.
