Note 1: Use of the post-divider is required for frequencies lower than 20 MHz on CLK+ & CLK- outputs. Use of the post-divider

is recommended for output frequencies lower than 65 MHz.

Note 2: Using load circuit of Figure 6. Duty cycle measured at zero crossings of difference voltage between CLK+ and CLK-.

Note 3: Cumulative jitter is defined as the maximum error (in the time domain) of any CLK edge, at any point in time, compared

with the equivalent edge generated by an ideal frequency source.

ICS laboratory testing indicates that the typical value shown above can be treated as a maximum jitter specification in

virtually all applications. Jitter performance can depend somewhat on circuit board layout, decoupling, and register

programming.
