4.6. Signals
| Signal | Direction | Width | Description | 
|---|---|---|---|
| Clock and Reset Signal | |||
| mgmt_clk | Input | 1 | 
        Input clock for: 
         
 | 
| pll_ref_clk | Input | 1 | This reference clock is used by the Clock Data Recovery (CDR) unit in the transceiver. It serves as a reference for the CDR to recover the clock from the serial line. The frequency of this clock must match the frequency you select in the IP parameter editor. | 
| iopll_ref_clk | Input | 1 | This clock is used as a reference clock for the IOPLL user clock. | 
| mgmt_reset_n | Input | 1 | Design example asynchronous master reset. Assert this reset signal to reset the overall design example system. This is an active low signal. | 
| snk_core_reset_n | Output | 1 | Demo management module asserts this signal to reset traffic checker module. | 
| src_core_reset_n | Output | 1 | Demo management module asserts this signal to reset traffic generator module. | 
| Data Signal | |||
| rx[n] | Input | Based on Number of Lanes value | This vector carries the transmitted streaming data from the core. n represents the number of lanes. | 
| tx[n] | Output | Based on Number of Lanes value | This vector carries the transmitted streaming data to the core. n represents the number of lanes. | 
| Status Signal | |||
| rx_activity_n | Output | 1 | This single bit signal indicates that the data is valid. | 
| tx_activity_n | Output | 1 | This single bit signal indicates that the data is valid. | 
| snk_link_up_n | Output | 1 | The core asserts this signal to indicate that the core initialization is complete and is ready to receive user data. | 
| src_link_up_n | Output | 1 | The core asserts this signal to indicate that the core initialization is complete and is ready to transmit user data. |
