Terminal Side Timing Characteristics
Note 1: CLKI symmetry is measured about the 1.4VDC threshold in order to assure symmetric output waveforms.
Note 2: The clock input can be 6, 8, or 34 MHz (refer to page 5).
Note 1: CKLO symmetry is measured about the 50% amplitude point.
Note 2: The clock output can be 6, 8, or 34 MHz (refer to page 4).
