5.1. GTS Interlaken IP Clock and Reset Interface Signals

Table 21.  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.
