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.
