5.1. GTS Interlaken IP Clock and Reset Interface Signals
Signal Name | Width (Bits) | I/O Direction | Available In | Description |
---|---|---|---|---|
pll_ref_clk | 1 | Input | Interlaken mode | TX PLL/RX CDR reference clock used by PMA. |
tx_usr_clk | 1 | Input | Interlaken mode | Transmit side user data interface clock. The lower frequency of tx_usr_clk increases the latency of data path. You can also connect it to clk_tx_common. |
rx_usr_clk | 1 | Input | Interlaken mode | Receive side user data interface clock. The lower frequency of rx_usr_clk increases the latency of data path. You can also connect it to clk_rx_common. |
clk_tx_common | 1 | Output | Interlaken mode | Transmit PCS common lane clock driven by the SERDES transmit PLL. |
clk_rx_common | 1 | Output | Interlaken mode | Receive PCS common lane clock driven by CDR in transceiver. The valid frequencies for clk_rx_common are same as clk_tx_common. |
o_src_rs_req | Number of lanes | Output | Interlaken mode | Request from the SRC_Lane to the SRC_Shoreline_Sequencer when it wants to toggle a reset. This port is exported to the Interlaken top to be connected to an external SRC_Shoreline_Sequencer manually by user |
i_src_rs_grant | Number of lanes | Input | Interlaken mode | Grant to the SRC_Lane. The SRC_Shoreline_Sequencer to provide a grant to only request at a time. This port is exported to the Interlaken top to be connected to an external SRC_Shoreline_Sequencer manually by the user. |
reset_n | 1 | Input | Interlaken mode | Active-low asynchronous reset signal for IP only. You must put the IP in reset when resetting the Direct-PHY to prevent IP corruption while waiting for Direct-PHY to be fully in reset. |
tx_rst_n | 1 | Input | Interlaken mode | Active low asynchronous reset for Direct-PHY. This reset drives the tx_desired_state of the SRC. |
rx_rst_n | 1 | Input | Interlaken mode | Active low asynchronous reset for Direct-PHY. This reset drives the rx_desired_state of SRC. When you perform a Serial Internal Loopback CPI Command, this reset must be held low until TX is fully out-of-reset. |
tx_rst_ack_n | 1 | Output | Interlaken mode | Active low asynchronous reset acknowledge signal. Indicates that soft reset controller has successfully entered reset mode for TX side and you can now release the tx_rst_n signal. This signal stays low until you release the tx_rst_n signal. |
rx_rst_ack_n | 1 | Output | Interlaken mode | Active low asynchronous reset acknowledge signal. Indicates that soft reset controller has successfully entered reset mode for RX side and you can now release the rx_rst_n signal. This signal stays low until you release the rx_rst_n signal. |
tx_usr_srst | 1 | Output | Interlaken mode | Transmit-side reset output signal. Indicates the transmit side user data interface is under reset. This signal is synchronous with tx_usr_clk. |
rx_usr_srst | 1 | Output | Interlaken and Interlaken Look-aside mode | Receive-side reset output signal. Indicates the receive side user data interface is under reset. This signal is synchronous with rx_usr_clk. |
i_pma_cu_clk | 1 | Input | Interlaken mode | PMA Control Unit clock output, one per bank for each side of the device. |
