AR# 52844: 7 Series GTX GTH Production Silicon - Correct setup when OOB is not used
7 Series GTX GTH Production Silicon - Correct setup when OOB is not used
Aurora channel with Production silicon is stuck with CHANNEL_UP = '0'. It was working fine with GES silicon.
It seems that the RXBUFFER is always in reset, RXDATAis stuck, and RXRECCLK (RXOUTCLK) is correctly toggling.
RXBYTEISALIGNED is not asserted as expected, but the datais good.
The channel was working properly with GES silicon.
In Production silicon, PCS_RSVD_ATTR=1 enables the electrical idle detect circuit. In GES and previous silicon, the idle detect circuit is always enabled. For all silicon, if RXBUF_RESET_ON_EIDLE = TRUE, an internal automatic RX Buffer Reset is applied when the Electrical Idle condition is detected.
For all protocols not using OOB or Electrical Idle detection, please set the following parameters:
To power down OOB signal detector:
PCS_RSVD_ATTR = '0'
When OOB is powered down, downstream circuits must ignore OOB detector output:
