7.1.6.3. IEEE 1588v2 RX Timestamp Signals
Signal | I/O | Width | Description |
---|---|---|---|
rx_ingress_timestamp_96b_data_n | O | 96 | Carries the ingress timestamp on the receive datapath. Consists of 48-bit seconds field, 32-bit nanoseconds field, and 16-bit fractional nanoseconds field. The MAC presents the timestamp for all receive frames and asserts this signal in the same clock cycle it asserts rx_ingress_timestamp_96b_valid. |
rx_ingress_timestamp_96b_valid | O | 1 | When asserted, this signal indicates that rx_ingress_timestamp_96b_data contains valid timestamp. For all receive frame, the MAC asserts this signal in the same clock cycle it receives the start of packet (avalon_st_rx_startofpacket is asserted). |
rx_ingress_timestamp_64b_data | O | 64 | Carries the ingress timestamp on the receive datapath. Consists of 48-bit nanoseconds field and 16-bit fractional nanoseconds field. The MAC presents the timestamp for all receive frames and asserts this signal in the same clock cycle it asserts rx_ingress_timestamp_64b_valid. |
rx_ingress_timestamp_64b_valid | O | 1 | When asserted, this signal indicates that rx_ingress_timestamp_64b_data contains valid timestamp. For all receive frame, the MAC asserts this signal in the same clock cycle it receives the start of packet (avalon_st_rx_startofpacket is asserted). |
