Notes:
1.
Current draw is independent of supply voltage.
2.
No under- or overshoot is allowed.
3.
LVPECL outputs require nominal VDD ≥ 2.5 V.
4.
This is the amount of leakage that the 3-level inputs can tolerate from an external driver. See Si53xx Family
Reference Manual for more details.
5.
LVPECL, CML, LVDS and low-swing LVDS measured with Fo = 622.08 MHz.
