10.0 Jitter Transfer Characteristics of the XRT8001
The definition of “Jitter Transfer Characteristics” (of the
XRT8001) is the amount of “output” jitter that the
XRT8001 produces (at the “CLK1” and “CLK2” out-
puts), when provided with a certain amount of jitter at
the FIN input pin.
The “Jitter Transfer Characteristics” of the XRT8001
are presented in Figure 25 (for 3.3V applications) and
Figure 26(for 5.0V applications).
