1. Stresses greater then those listed under Maximum Ratings may cause permanent damage to the device. This is a stress rating only and
functional operation of the device at these or any other conditions above those indicated in the operational sections of the this specifications is
not implied. Exposure to absolute maximum rating conditions for extended periods may affect reliability.
2. θJA and θJB values are determined for a 4-layer board in still-air, unless otherwise stated.

Note:
1. See Switching Waveforms
2. All clock output should have the same loading to achieve zero delay between the input and outputs and zero output-to-output skew. Since the CLKOUT pin is the
internal feedback to the PLL, its relative loading can adjust to input-to-output delay. If input-to-output delay adjustments are needed, the CLKOUT load may be
changed to vary the delay between the REF input to the clock outputs. Output-to-output skew includes CLKA1-4 and CLKB1-4.
3. Specifications are guaranteed by design and not production tested.
4. Measured at 100MHz.
5. Measured with 16-Pin SOIC package
