100G Interlaken IP Core Reset Signals |
|||
reset_n |
Input |
1 |
Active-low reset signal for the 100G Interlaken IP core. Intel® recommends that you hold this signal low for at least the duration of two mm_clk cycles, to ensure the reset sequence proceeds correctly. |
reconfig_reset | Input |
1 |
Reset signal for the Intel® Arria® 10 transceiver reconfiguration interface. This signal is available only in IP core variations that target an Intel® Arria® 10 device. |
srst_tx_common |
Output |
1 |
Synchronous reset signal that the IP core asserts high while the transmitter is initializing. This signal is synchronous with clk_tx_common. This signal goes low to indicate that the transceiver PLL has locked to the reference clock. The TX PCS and the TX MAC are held in reset while the srst_tx_common reset signal is asserted. You can use this signal for diagnostic purposes. |
srst_rx_common |
Output |
1 |
Synchronous reset that is active at startup. This signal is synchronous with clk_rx_common. This signal goes low to indicate that the transceiver PLL has achieved lock and the recovered clock has locked to data in normal operation, this signal is deasserted after the transceiver completes its reset sequence. The RX PCS and the RX MAC are held in reset while the srst_rx_common reset signal is asserted. This signal is also active in the event of a serious clock data recovery failure on any of the RX lanes. |
tx_usr_srst |
Output |
1 |
Transmit side reset output signal. Indicates the transmit side user data interface is resetting. This signal is synchronous with tx_usr_clk. Your application can use this signal to reset any status counters you may maintain in the tx_usr_clk domain. |
rx_usr_srst |
Output |
1 |
Receive side reset output signal. Indicates the receive side user data interface is resetting. This signal is synchronous with rx_usr_clk. Your application can use this signal to reset any status counters you may maintain in the rx_usr_clk domain. |
