10000 cycles.

(7)

Jitter depends on configuration. Jitter data is for input frequency = 27 MHz, fVCO = 108 MHz, fOUT = 27 MHz (measured at Y2).

(8)

The tsk(o) specification is only valid for equal loading of each bank of outputs, and the outputs are generated from the same divider.

(9)

odc depends on output rise and fall time (tr/tf); data sampled on rising edge (tr)

(10) SDA and SCL pins are 3.3 V tolerant.
