5.1. Reset Initialization

The F-Tile JESD204C base core and transport layer require various resets for the IP and transceiver. All the resets in the core assert asynchronously and deassert synchronously.
Table 15.   F-Tile JESD204C IP Resets
Reset Signal Clock Domain Description

j204c_tx_rst_n

j204c_rx_rst_n

Asynchronous Assertion of these signals resets all logic in the IP (MAC, TL, FIFOs).

j204c_tx_avs_rst_n

j204c_rx_avs_rst_n

TX/RX Avalon® memory-mapped reset for CSR

(j204c_tx_avs_clk/j204c_rx_avs_clk)

  • This reset is for the Avalon® memory-mapped slave interface, which consists of the Configuration and Status Register (CSR) blocks.
  • After this reset deasserts, configuration phase starts. You can program the CSR register values if a non-default value is required.

j204c_tx_rst_ack_n

j204c_rx_rst_ack_n

Asynchronous These signals acknowledge the state of j204c_tx_rst_n and j204c_rx_rst_n. The reset sequence completion is indicated by the assertion of these signals.
reconfig_xcvr_reset Asynchronous

Transceiver reconfiguration clock.

Active high signal. During duplex mode, both TX and RX share the same reconfiguration pins.

Intel recommends that you tie this signal to tx_avs_rst_n.
