1.4. JESD204B IP Core and AD9250 Configurations

The JESD204B IP core parameters (L, M and F) in this hardware checkout are natively supported by the AD9250 module's quick configuration register at address 0x5E. The transceiver data rate, sampling clock frequency, and other JESD204B parameters complies with the AD9250 operating conditions.

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

Data Pattern

PRBS-9

Ramp 5

3 The device clock is used to clock the transceiver.
4 The frame clock and link clock is derived from the device clock using an internal PLL.
5 The ramp pattern is used in deterministic latency measurement test cases DL.1, DL.2, and DL.3 only.
