Notes:
1. These parameters are not 100% tested, but are evaluated at initial characterization and at any time the design is modified
where frequency may be affected.
2. See Switching Test Circuit for test conditions. Switching waveforms illustrate true clocks only. Switching waveforms can be
used to illustrate both synchronous and asynchronous clock timing. For example, tSS is the tS parameter for synchronous
clocks and tSA is the tS parameter for asynchronous clocks.
3. Parameters measured with 16 outputs switching.
