Why do the tx_path_delay_10g_data and tx_path_delay_1g_data signal descriptions refer to a data width of 16/22 for the Arria® V and Stratix® V  devices in the Low Latency Ethernet 10G MAC User Guide?

Description

Due to a mistake in Table 5-16: IEEE 1588v2 Egress Transmit Signals" of the Altera® Low Latency Ethernet 10G MAC User Guide (PDF), the tx_path_delay_10g_data and tx_path_delay_1g_data signal descriptions refer to a data width of 16/22 for the Arria® V and Stratix® V devices.

tx_path_delay_10g_data tx_path_delay_1g_data signal signals should refer to a data width of 15/21.

Resolution

This problem has already been fixed in a new version of the Low Latency Ethernet 10G MAC User Guide (PDF).
