The receiver must meet certain jitter transfer specifications between the input and
output jitter as a function of frequency. These specifications are only intended to
be met with the use of a jitter attenuator. Because the CX2833i does not contain a
jitter attenuator, one will have to be supplied externally. For reference purposes,
the specifications are discussed in the following documents and shown in
2-9.
