4.11. 10GBASE-KR PHY Clock and Reset Interfaces

This topic provides a block diagram of the 10GBASE-KR clock and reset connectivity and describes the clock and reset signals.

Use the Transceiver PHY Reset Controller IP Core to automatically control the transceiver reset sequence. This reset controller also has manual overrides for the TX and RX analog and digital circuits to allow you to reset individual channels upon reconfiguration.

If you instantiate multiple channels within a transceiver bank they share TX PLLs. If a reset is applied to this PLL, it will affect all channels. Altera recommends leaving the TX PLL free-running after the start-up reset sequence is completed. After a channel is reconfigured you can simply reset the digital portions of that specific channel instead of going through the entire reset sequence. If you are not using the sequencer and the data link is lost, you must assert the rx_digitalreset when the link recovers. For more information about reset, refer to the "Transceiver PHY Reset Controller IP Core" chapter in the Altera Transceiver PHY IP Core User Guide.

The following figure provides an overview of the clocking for this core.

Figure 27.  Clocks for Standard and 10G PCS and TX PLLs

To ensure proper functioning of the PCS, the maximum PPM difference between the pll_ref_clk_10g and the xgmii_tx_clk clock inputs is 0 PPM.

The following table describes the clock and reset signals. The frequencies of the XGMII clocks increases to 257.8125 MHz when you enable 1588.

Table 31.  Clock and Reset Signals
Signal Name Direction Description
rx_recovered_clk Output The RX clock which is recovered from the received data. You can use this clock as a reference to lock an external clock source. Its frequency is 125 or 257.8125 MHz.
tx_clkout_1g Output GMII TX clock for the 1G TX parallel data source interface. The frequency is 125 MHz.
rx_clkout_1g Output GMII RX clock for the 1G RX parallel data source interface. The frequency is 125 MHz.
rx_coreclkin_1g Input Clock to drive the read side of the RX phase compensation FIFO in the Standard PCS. The frequency is 125 MHz.
tx_coreclkin_1g Input Clock to drive the write side of the TX phase compensation FIFO in the Standard PCS. The frequency is 125 MHz.
pll_ref_clk_1g Input Reference clock for the PMA block for the 1G mode. Its frequency is 125 or 62.5 MHz.
pll_ref_clk_10g Input Reference clock for the PMA block in 10G mode. Its frequency is 644.53125 or 322.265625 MHz.
pll_powerdown_1g Input Resets the 1Gb TX PLLs.
pll_powerdown_10g Input Resets the 10Gb TX PLLs.
tx_analogreset Input Resets the analog TX portion of the transceiver PHY.
tx_digitalreset Input Resets the digital TX portion of the transceiver PHY.
rx_analogreset Input Resets the analog RX portion of the transceiver PHY.
rx_digitalreset Input Resets the digital RX portion of the transceiver PHY.
usr_an_lt_reset Input Resets only the AN and LT logic. This signal is only available for the 10GBASE‑KR variants.
usr_seq_reset Input Resets the sequencer. Initiates a PCS reconfiguration, and may restart AN, LT or both if these modes are enabled.
usr_fec_reset Input When asserted, resets the 10GBASE-KR FEC module.
usr_soft_10g_pcs_reset Input When asserted, resets the 10G PCS associated with the FEC module.
