Notes to Figure 6–31 :
(1) For more information, refer to the Stratix GX Analog Description chapter.
(2) Receiver PLL lock indicator. For rx_locked, Low = receiver PLL locked to reference clock.
(3) The rx_signaldetect is only available in XAUI or GigE mode. Refer to the Stratix GX Analog Description chapter
for additional information.
(4) Indicates when the word aligner has aligned to the byte boundary. The rx_syncstatus signal goes high for one
rx_clkout
period when the word aligner aligns to the new byte boundary.
(5) The rx_patterndetect is similar to the rx_syncstatus, with the exception that the rx_patterndetect
asserts only when the Word Alignment pattern appears in the data stream within the synchronized byte boundary.
