AFC/RCW
AFC operation and clock regeneration range specification signal input.
As shown in Figure 5, AFC information is reset when AFC/RCW and RPR go to "1" level. The
AFC operation starts after a certain time elapses.
The average number of AFC operation times is small when RPR is at "1" level.
The average number of AFC operation times is large when RPR is at "0" level.
If AFC/RCW is at "0" level, DPLL will not adjust the phase.
