5.3. IP Port List

Table 81.  GTS Reset Sequencer IP Port List

N is number of channels used.

Signal Name Direction Width Description
i_src_rs_req Input N Request from SRC to GTS Reset Sequencer IP for reset operation. Asserts when there is a request to toggle reset.
o_src_rs_grant Output N Grant from GTS Reset Sequencer IP to SRC. Asserts when the reset request is granted by the Reset Sequencer.
i_src_rs_priority Input N
Binary priority input
  • 0 - Low priority
  • 1 - High priority

This port used to set priority for a channel that you need to prioritize the reset sequence when there are multiple channels being reset simultaneously. You must tie the input to 0 except for the priority channel which needs to be set to 1.

o_pma_cu_clk Output 1
PMA control unit clock output. This clock port must be connected to the GTS PMA/FEC Direct PHY IP and all other protocol IPs.
Note: o_pma_cu_clk signal is only for use by the PMA control unit and you must not use it elsewhere.
i_refclk_bus_out Input 1 Reference clock failed status signal from the GTS PMA/FEC Direct PHY IP or other protocol IPs (non- PCIe* ).
o_shoreline_refclk_fail_stat Output 1 Reference clock fail status indication from the GTS Reset Sequencer IP to user logic.
