rx_locktorefclk signals asserted and the rx_locktodata signal de-asserted
during this time period. After you de-assert the pll_powerdown signal, the
transmitter PLL starts locking to the transmitter input reference clock.
(marker 3), de-assert the tx_digitalreset signal (marker 4). For the receiver
operation, after de-assertion of the busy signal, wait for a minimum of two parallel
clock cycles to de-assert the rx_analogreset signal. After the rx_analogreset
signal is de-asserted, the receiver CDR of each channel starts locking to the
receiver input reference clock because rx_locktorefclk is asserted.
rx_pll_locked signal of each channel may go high at different times with respect
to each other (indicated by the slashed pattern at marker 7).

de-assert rx_locktorefclk and assert rx_locktodata (marker 8). At this point, the
receiver CDR of all the channels enters into lock-to-data mode and starts locking to
the received data.
