6.1.11.2. IEEE 1588v2 TX Timestamp Signals
Signal | I/O | Width | Description |
---|---|---|---|
tx_egress_timestamp_96b_data_n | O | 96 | A transmit interface signal. This signal carries requested timestamp of transmitted frame with fingerprint tx_egress_timestamp_96b_fingerprint. Consists of 48-bit seconds field, 32-bit nanoseconds field, and 16-bit fractional nanoseconds field. |
tx_egress_timestamp_96b_valid | O | 1 | A transmit interface signal. When asserted, this signal indicates that a timestamp is obtained and a timestamp request is valid for the particular frame. Assert this signal in the same clock cycle as the start of packet (avalon_st_tx_startofpacket is asserted). |
tx_egress_timestamp_96b_fingerprint | O | n | Configurable width fingerprint that returns with correlated timestamps. The signal width is determined by the TSTAMP_FP_WIDTH parameter (default parameter value is 4). |
tx_egress_timestamp_64b_data | O | 64 | A transmit interface signal. This signal requested timestamp of transmitted frame with fingerprint tx_egress_timestamp_64b_fingerprint. Consists of 48-bit nanoseconds field and 16-bit fractional nanoseconds field. |
tx_egress_timestamp_64b_valid | O | 1 | A transmit interface signal. When asserted, this signal indicates that a timestamp is obtained and a timestamp request is valid for the particular frame. Assert this signal in the same clock cycle as the start of packet (avalon_st_tx_startofpacket or avalon_st_tx_startofpacket_n is asserted). |
tx_egress_timestamp_64b_fingerprint | O | n | Configurable width fingerprint that returns with correlated timestamps. The signal width is determined by the TSTAMP_FP_WIDTH parameter (default parameter value is 4). |
