The transceiver allows you to reset the entire RX at any time by sending GTRXRESET and PCSRSVDIN[10] an active-High pulse. These conditions must be met when using GTRXRESET:

  1. RXRESETMODE must be set to use sequential mode.
  2. All RXPMARESETMASK , PCSRSVDIN[9:8] (RXDAPIRESETMASK), and RXPCSRESETMASK bits should be held to High during the reset sequence before RXRESETDONE is detected High.
  3. The associated PLL must indicate locked.
  4. The guideline for this asynchronous GTRXRESET pulse width is one period of the reference clock.
