WebSSC support GTY Transceiver. Hi, I have a Kintex Ultrascale \+ device (KU3P) running a custom protocol @ 12.5 Gbit/s 8b/10b encoding. Does the Transceiver support tx and rx spread spectrum clocking? The design is only for loopback (outside FPGA, only one FPGA) intended: FPGA_TX (Pattern Generator) -> Custom ASIC -> FPGA RX (Pattern … WebDue to some reason, the QPLLs in the GTYs are not locked. But my question is about RXRESETDONE and TXRESETDONE (outputs of the primitive). I observed that the RXRESETDONE and TXRESETDONE are HIGH even when the QPLL is not locked. The reset done outputs of the gtwiz reset helper block are still low.

WebAccording to AR#63026, the phase noise mask is a preferred method for specifying jitter of the UltraScale GTH/GTY reference clock. ... Does this mean that if i use the QPLL the reference clock should be even more "precise"? Not necessarily. Since the 50MHz point is excluded from Table 102 for the QPLL specifications then we must assume that ...

WebA workaround to my design is to have a fabric clock derived from the MAC GTY QPLL reference clock. To do so I need an additional GTY_COMMON and GTY_CHANNEL: the GTY_COMMON will generate my desired clock (trough QPLL0/1) and that clock will be routed trough GTY_CHANNEL into the fabric. WebBased on the fact that we do see RXUSERRDY go high, we think that the problem can be traced back to the RX Fabric Clock generator (the reset process might be getting stuck on RXPCSRESET, and we're not getting RXOUTCLKPCS to drive the gtpowergood_delay block, which is why we see gtpowergood go high at the primitive but not on the outside).

WebI find that Aurora 64//66b IP uses GTY and has configurable line rate.
