1.3.2. JESD204C Intel® FPGA IP and ADC Configurations

The JESD204C Intel® FPGA IP parameters (L, M, and F) in this hardware checkout are natively supported by the AD9081 device configuration registers. The transceiver data rate, sampling clock frequency, and other JESD204C parameters comply with the AD9081 operating conditions.

The hardware checkout testing implements the JESD204C Intel® FPGA IP with the following parameter configurations.

Global setting for below configuration:
  • E = 1
  • CF = 0
  • FCLK_MULP = 2
  • WIDTH_MULP = 4
  • Subclass = 0
  • SH_CONFIG = CRC-12
  • FPGA Management Clock (MHz) = 100

8 Data rate = ADC rate x decimation factor.
9 Lane rate = (M/L) x N' x (66/64) x data rate.
10 The FPGA device clock is used to clock the core PLL and the transceiver.
11 The link clock and the frame clock are derived from the device clock using the core PLL.
