Embedded Clock Rate

fOUT/6

fOUT is the nominal output frequency of the output

with the embedded clock

Duty Cycle Deviation

tSYS = 1/(fSYS); the system clock frequency is fOSC/J × K × D,

where fOSC is the frequency of the system clock

oscillator connected to the XOA/XOB pins, J is the

SYSCLK input divider ratio, K is the feedback divider

ratio, and D is the SYSCLK doubler setting; D = 2 if the

SYSCLK doubler is enabled, and D = 1 if it is disabled;

tSYS must be in the 414 ps to 440 ps range; fOUT is the

output frequency

DC Balanced Modulation

REFERENCE MONITORS

Reference Monitor

Loss of Reference Detection Time

4.9 + 0.13 × tPFD

μs

tPFD is the nominal phase detector period,

R/fREF, where R is the frequency division factor

determined by the R divider, and fREF is the

frequency of the active reference

Frequency Out of Range Limits

1.5 × 107

ppb

Parts per billion (ppb) is defined as

(Δf/fREF) × 109, where Δf is the frequency

deviation, and fREF is the reference input

frequency; programmable with the lower

bound, subject to quality of the system clock

(or the source of system clock compensation);

1.5 × 107 is equivalent to 1.5%
