All typical values are at respective nominal VDD.
Jitter depends on configuration. Jitter data is for input frequency = 27 MHz, fVCO = 108 MHz, fOUT = 27 MHz (measured at Y2).
Y1 supplied by PLL1 and configured to same frequency as Y2.
The tsk(o) specification is only valid for equal loading of each bank of outputs, and the outputs are generated from the same divider.
odc depends on the output rise and fall time (tr and tf); data sampled on the rising edge (tr)
SDA and SCL pins are 3.3-V tolerant.
