5.1.2. F-Tile JESD204C RX Reset Sequence

Figure 9.  F-Tile JESD204C RX Reset Sequence

The descriptions below correspond to the Figure 9:

  1. The user logic asserts the F-Tile JESD204C IP and configuration reset to the F-Tile JESD204C IP RX, j204c_rx_avs_rst_n = 1, j204c_rx_rst_n = 0, and j204c_reconfig_reset = 1.
    Note: If you assert j204c_rx_avs_rst_n and reconfig_xcvr_reset, j204c_rx_rst_n is required to be asserted as well. You can opt to assert j204c_rx_rst_n without asserting j204c_rx_avs_rst_n and reconfig_xcvr_reset.
  2. The user logic deasserts j204c_rx_avs_rst_n and reconfig_xcvr_reset and perform configurations of the PHY and IP. At the same, wait for IOPLL to lock.
  3. After all relevant PHY channels are fully in reset, the IP core asserts j204c_rx_rst_ack_n to the user logic. Knowing the relevant channels are in proper reset states, the user logic can release the reset to the IP core when possible (j204c_rx_rst_n = 1). Use j204c_rx_rst_ack_n as an indicator to deassert j204c_rx_rst_n = 1.
  4. The user logic deasserts the IP reset (j204c_rx_rst_n = 1).
  5. The IP asserts j204c_rx_avst_valid = 1 when alignment and deskew is achieved, and deskew is complete. The F-Tile JESD204C RX IP core is operational.
  6. At any time when you require a reset to the MAC and PHY, you must wait for j204c_rx_rst_ack_n = 1. Assertion of j204c_rx_rst_n = 0 resets the MAC and PHY in the IP core.
  7. The IP core asserts j204c_rx_rst_ack_n = 0 to indicate that reset sequence is complete.
