AC Characteristics

Table 3: Data Path

Note: Unless otherwise stated, all specifications are guaranteed but not tested.

Note 1: Skew between any two input channels to a given output.

Note 2: Skew between any two output channels from the same input channel.

Note 4: Broadband jitter added to a jitter-free signal; jitter is primarily in the form of ISI for random data
