1.4. JESD204B IP Core and ADC Configurations

The JESD204B IP Core parameters (L, M, and F) in this hardware checkout are natively supported by the AD9625 device's quick configuration register at address 0x05E. The transceiver data rate, sampling clock frequency, and other JESD204B parameters comply with the AD9625 operating conditions.

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

Global setting for all configuration:

  • CS = 0
  • CF = 0
  • Subclass = 1
  • FPGA Management Clock (MHz) = 100
  • Character Replacement = Enabled
  • PCS Option = Hard PCS

3 The device clock is used to clock the transceiver.
4 The frame clock and link clock are derived from the device clock using an internal PLL.
5 The 16-bit test pattern is an output from the JESD204 test pattern generator block in the AD9625.
