The step numbers correspond to the numbers in the following figure.
  1. Perform the following steps:
    1. Assert tx_analogreset, pll_powerdown, and tx_digitalreset while pll_cal_busy and tx_cal_busy are low.
    2. Deassert pll_powerdown after a minimum duration of 1 μs. This step can be delayed and deasserted at the same time you deassert tx_a
