Description
Conditions
T_LOCK
T_DLOCK
Initial PLL lock
Clock recovery phase acquisition and
adaptation time for decision
feedback equalizer (DFE).
Clock recovery phase acquisition and
adaptation time for low-power mode
(LPM) when the DFE is disabled.
After the PLL is locked to
the reference clock, this is
the time it takes to lock
the clock data recovery
(CDR) to the data present
at the input.
