Table 25.  Transceiver Signals
Signal Width Clock Domain Direction Description
xcvr_refclk_sel 12 1 tx_coreclk Input

Transceiver reference clock select signal that selects which clock to be used.

  • 0 = xcvr_refclk
  • 1 = xcvr_refclk_alt

Applicable only when you enable the Tx PLL Dynamic Switching option.

tx_pll_locked 12 1 Output PLL locked signal (TX PLL0) for the Native PHY IP core.
tx_pll_locked_alt 12 1 Output

PLL locked signal (TX PLL1) for the Native PHY IP core.

Applicable only when you enable the Tx PLL Dynamic Switching option.

reconfig_to_xcvr 12 70N Input Dynamic reconfiguration input for the Native PHY IP core, where N is the reconfiguration interface.
  • N = 1 for receiver
  • N = 2 for transmitter and bidirectional
reconfig_to_xcvr_b 13 70N Input

Dynamic reconfiguration input for the Native PHY IP core, where N is the reconfiguration interface.

  • N = 1 for receiver
  • N = 2 for transmitter and bidirectional
reconfig_from_xcvr 46N Output

Dynamic reconfiguration output for the Native PHY IP core, where N is the reconfiguration interface.

  • N = 1 for receiver
  • N = 2 for transmitter and bidirectional
Note: Not applicable for Agilex™ 7 F-Tile, Arria® 10, Cyclone® 10 GX, and Stratix® 10 devices.
reconfig_from_xcvr_b 13 46N Output

Dynamic reconfiguration output for the Native PHY IP core, where N is the reconfiguration interface.

  • N = 1 for receiver
  • N = 2 for transmitter and bidirectional
rx_sdi_start_reconfig 14 1 rx_coreclk Output Request to start dynamic reconfiguration. This signal stays asserted until rx_sdi_reconfig_done indicates that the reconfiguration process is complete.
rx_sdi_reconfig_done 14 1 Input

Indicates that dynamic reconfiguration has completed.

This signal should connect to the reconfiguration status signal of the external transceiver reconfiguration management.
  • For Agilex™ 7 F-Tile, Arria V, Cyclone V, and Stratix V devices, assertion of this signal indicates to the receiver that the process is done.
  • For Arria® 10, Cyclone® 10 GX, and Stratix® 10 devices, deassertion of this signal indicates to the receiver that the process is done.
rx_ready 14 1 Input

Status signal from the transceiver reset controller to indicate when RX PHY sequence is complete.

gxb_ltr 14 1 rx_coreclk Output

Control signal to the transceiver rx_set_locktoref input signal.

Assertion of this signal programs the Rx CDR to lock manually to reference mode.

gxb_ltd 14 1 rx_coreclk Output

Control signal to the transceiver rx_set_locktodata input signal.

rx_ready_b 1 Input

Status signal from Transceiver Reset Controller to indicate when Rx PHY reset sequence is complete for link B

For HD-SDI dual link receiver protocol configuration only. (Not supported anymore on A10 from 16.1 onwards).
gxb_ltr_b 1 rx_coreclk Output

Control signal to transceiver rx_set_locktoref input port. When asserted, programs the RX CDR to manual lock to reference mode.

For HD-SDI dual link receiver protocol configuration only. (Not supported anymore on A10 from 16.1 onwards).
gxb_ltd_b 1 rx_coreclk Output

Control signal to transceiver rx_set_locktodata input port. When asserted, programs the RX CDR to manual lock to data mode.

For HD-SDI dual link receiver protocol configuration only. (Not supported anymore on A10 from 16.1 onwards).
rx_xcvr_reset_ack 1 Input Status signal from transceiver indicating that the Rx transceiver is fully in reset
11 Applicable for HD-SDI dual link configuration only.
12 Not applicable for Arria® 10, Cyclone® 10 GX, Stratix® 10, and Agilex™ 7 F-Tile devices.
13 For HD-SDI dual link configuration only. Not applicable for Agilex™ 7 F-Tile, Arria® 10, Cyclone® 10 GX, and Stratix® 10 devices.
14 Applicable for dual rate, triple-rate, and multi-rate modes only.
15 Applicable only for Arria® 10, Cyclone® 10 GX, Stratix® 10, and Agilex™ 7 F-Tile devices.
