Description
Master reset pin, active low. Asserting this signal
causes the entire SerialLite II MegaCore function,
mreset_n
Input
Asynchronous
including the Atlantic FIFO buffers, to be reset.
For Arria V, Cyclone V, and Stratix V designs, hold this
signal asserted until the Custom PHY asserts the
tx_ready and rx_ready output ports.
Force training patterns to be sent. Negate once the
ctrl_tc_force_train
Input
tx_coreclock
receiver has locked. Only used in self-synchronizing
mode. Otherwise, this signal is currently reserved (tie
this signal to 1'b0 ).
stat_tc_pll_locked
Output
tx_coreclock
PLL locked signal. Indicates that the ALTGX PLL has
locked to the trefclk .
stat_rr_link
Output
rrefclk
Link Status. When high, the link is enabled.
Notes to Table 4–5 :
(1) n = RX number of lanes
(2) m = TX Number of lanes
(3) In broadcast mode, these signals will have the corresponding receiver function number post-fixed. For example, err_rr_crc0 is the CRC error
signal from SerialLite II receiver block 0.
(4) This signal is removed in configurations targeted for Arria V, Cyclone V, and Stratix V devices due to the exclusion of hard transceivers.
Table 4–6 shows the transceiver megafunction signals.
f For more information on Altera gigabit transceiver (ALTGX ) megafunction, refer to
the Arria II GX Transceiver Architecture section in volume 2 of the Arria II GX Device
Handbook , and the Stratix IV Transceiver Architecture section in volume 2 of the
Stratix IV Device Handbook .
