After powerup or RESET, the LOCKDET signal will go
active, signifying that the PLL has locked to the clock
provided on the T

input. The FIFO is initialized
on the third PIC
LK
after LOCKDET goes active. The
PC

-to-PIC
LK
delay (t
D
) can have any value before the
FIFO is initialized. The t
D
is fixed at the third PICLK
after LOCKDET goes active. Once the FIFO is initial-
ized, PC
LK
and PIC
LK
cannot drift more than 5.2 ns;
tCH cannot be more than 5.2 ns.
