5.2. Reset Initialization

The GTS 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 14.   GTS 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.
