Reset Signal | Associated Clock | Description |
---|---|---|
jesd204_tx_avs_rst_n jesd204_rx_avs_rst_n |
jesd204_tx_avs_clk jesd204_rx_avs_clk |
This reset is associated with the jesd204_tx_avs_clk signal. This reset is an active low signal. You can assert this reset signal asynchronously but must deassert it synchronously to the jesd204_tx_avs_clk signal. After you deassert this signal, the CPU can configure the CSRs. This reset is associated with the jesd204_rx_avs_clk signal. This reset is an active low signal. You can assert this reset signal asynchronously but must deassert it synchronously to the jesd204_rx_avs_clk signal. After you deassert this signal, the CPU can configure the CSRs. |
jesd204_tx_rst_n jesd204_rx_rst_n |
Asynchronous | From User. Async Assertion and Deassertion. Assertion triggers reset sequence to MAC and PHY(Tile). Reset sequence completion indicated by assertion tx_rst_ack_n. Deassertion triggers out-of-reset sequence. Out of reset completion indicates by deassertion of tx_rst_ack_n. User is required to assert this reset if tx_avs_rst_n is asserted. Assertion triggers reset sequence to MAC and PHY(Tile). Reset sequence completion indicated by assertion rx_rst_ack_n. Deassertion triggers out-of-reset sequence. Out of reset completion indicates by deassertion of rx_rst_ack_n. User is required to assert this reset if rx_avs_rst_n is asserted. |
jesd204_tx_rst_ack_n jesd204_rx_rst_ack_n |
Asynchronous | To User to indicate the Tile fully in reset. Async Assertion and Deassertion. (IP uses avs_clk or reconfig_xcvr_clk internally) |
jesd204_tx_out_of_reset jesd204_rx_out_of_reset |
Asynchronous | To indicate the reset status of the SIP link layer. Async Assertion and Deassertion. (IP uses avs_clk or reconfig_xcvr_clk internally) User may optionally observe jesd204_tx_out_of_reset = 1 to indicate SIP out of reset to pulse SYSREF for subclass 1. User must synchronize this signal before use. User may optionally observe jesd204_rx_out_of_reset = 1 to indicate SIP out of reset to pulse SYSREF for subclass 1. User must synchronize this signal before use. 0: SIP in reset 1: SIP out of reset |
reconfig_xcvr_reset |
jesd204_tx_avs_clk jesd204_rx_avs_clk |
From User: XCVR reconfiguration reset. Active High. During duplex mode, both TX and RX share the same reconfig pins. User is recommended to tie this to tx_avs_rst_n. |
