12.10. Optional Reset Control and Status Interfaces for Deterministic Latency PHY

The following table describes the signals in the optional reset control and status interface. These signals are available if you do not enable the embedded reset controller.

Table 176.  Avalon-ST RX Interface
Signal Name Direction Description
pll_powerdown [<n>-1:0] Input When asserted, resets the TX PLL.
tx_digitalreset [<n>-1:0] Input When asserted, reset all blocks in the TX PCS.
tx_analogreset [<n>-1:0] Input When asserted, resets all blocks in the TX PMA.
tx_cal_busy [<n>-1:0] Output

When asserted, indicates that the initial TX calibration is in progress. It is also asserted if reconfiguration controller is reset. It will not be asserted if you manually re-trigger the calibration IP. You must hold the channel in reset until calibration completes.

rx_digitalreset [<n>-1:0] Input When asserted, resets the RX PCS.
rx_analogreset [<n>-1:0] Input When asserted, resets the RX CDR.
rx_cal_busy [<n>-1:0] Output When asserted, indicates that the initial RX calibration is in progress. It is also asserted if reconfiguration controller is reset. It will not be asserted if you manually re-trigger the calibration IP.
