(1) tPLD is the time required by the serializer to obtain lock when exiting power-down state with an active PCLK.
(2) tDDLT is the time required by the deserializer to obtain lock when exiting power-down state with an active PCLK.
(3) tDPJ is the maximum amount the period is allowed to deviate over many samples.
(4) tDCCJ is the maximum amount of jitter between adjacent clock cycles.
(5) Specification is ensured by characterization and is not tested in production.
(6) Specification is ensured by design and is not tested in production.
