6.4. Transceiver Signals

Table 20.  Transceiver Signals
Signal Width Clock Domain Direction Description
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.
  • Assertion 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
14 Applicable for dual rate, triple-rate, and multi-rate modes only.
