(1) All typical values are at respective nominal V_DD.

(2) 10000 cycles.

(3) Jitter depends on configuration. Data is taken under the following conditions: 1-PLL is f_IN = 27MHz and Y2/3 = 27MHz (measured at Y2); 3-PLL is f_IN = 27MHz, Y2/3 = 27MHz (measured at Y2), Y4/5 = 16.384MHz, and Y6/7 = 74.25MHz.

(4) The tsk(o) specification is only valid for equal loading of each bank of outputs, and outputs are generated from the same divider; data taking on rising edge (tr).

(5) odc depends on output rise and fall time (t_r/t_f).

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