Signal

Width

Clock Domain

Direction

Description

tx_serial_clk N N/A

Input

This signal is a high-speed serial clock input from the external transceiver PLL. The width is the same as the number of lanes specified in the parameter editor. Each bit of the vector corresponds to serial clock of the transmit channel.

N represents the number of lanes.

tx_pll_locked 1 N/A Input This signal indicates that all external transceiver PLLs are locked. If more than one external transceiver PLL is required for higher lanes, each instantiation outputs a bit that indicates whether the PLL providing the high-speed clock for a corresponding transceiver has achieved its lock status. The pll_locked output signal from the external transceiver PLLs should be ANDed together before being input to the IP core.
core_reset

1

N/A

Input

Asynchronous master reset for the core. Assert this signal high to reset the MAC layer, except for the fPLL that is available in standard clocking mode.

Intel recommends that you tie this signal to the phy_mgmt_clk_reset signal to reset the digital core, analog core, and the PLL core.

xcvr_pll_ref_clk

1

N/A

Input

This signal is present but unused in source-only variations; tie this signal to 1’b0.

user_clock

1

N/A

Input/Output

Clock for data transfers across the source core interface.

  • Input: Using advanced clocking mode
  • Output: Using standard clocking mode
user_clock_reset

1

user_clock

Input/Output

In the standard clocking mode, the core asserts this signal when the core_reset signal is high and deasserts this signal when the reset sequence is complete.

In the advanced clocking mode, asserts this signal to reset the adaptation module FIFO buffer.

  • Input: Using advanced clocking mode
  • Output: Using standard clocking mode
interface_clock_reset 1 user_clock Output

Clock for data transfer across the source core interface in the advanced clocking mode.

Available only in Advanced Clocking Mode.
link_up

1

user_clock

Output

The core asserts this signal to indicate that the core initialization is complete and is ready to transmit user data.

data

64xN

user_clock

Input

This vector carries the transmitted streaming data to the core.

N represents the number of lanes.

sync

8

 user_clock

Input

The sync vector is an 8 bit bus. The data value at the start of a burst and the end of a burst are captured and transported across the link.

The value at the end of a burst is to indicate the number of invalid 64-bit word in the previous data cycle. As such, for single-lane configuration, the value at the end of a burst is expected to be 0.

Note: This vector is not associated with Interlaken channelization or flow control schemes.
valid

1

user_clock

Input

This single bit signal indicates that the transmitted streaming data is valid.

start_of_burst

1

user_clock

Input

When the core is in burst mode operation, asserting this signal indicates that the information on the data vector is the beginning of a burst.

Because continuous mode is one long burst, in this mode the signal is asserted only once at the start of the data.

end_of_burst

1

user_clock

Input

When the core is in burst mode operation, asserting this signal indicates that the information on the data vector is the end of a burst.

You can optionally send an end of burst signal at the end of continuous mode.

error

4

user_clock

Output

This vector indicates an error or overflow in the source adaptation module’s FIFO buffer.

  • Bit 0: Source adaptation module’s FIFO buffer overflow
  • Bit 1: An SEU error occurred and was corrected (ECC enabled)

    Don't care (ECC disabled)

  • Bit 2: An SEU error occurred and cannot be corrected (ECC enabled)

    Don't care (ECC disabled)

  • Bit 3: A burst gap error occurred due to a mismatch in the BURST GAP parameter value and the gap between end of burst and start of burst.
crc_error_inject 1 user_clock Input This signal forces CRC-32 errors when CRC-32 error injection is enabled in the transceiver channels. The CRC-32 error injection is enabled via the transceiver reconfiguration controller.
