1. Measured using “Measurement Circuit” with f_OSC ≈ f₀ ± 30ppm, functions auto-start normally.
2. ε₁ = ε (1.2V) = |[f (1.2V) − f (1.5V)] / f (1.5V)|
ε₂ = ε (1.7V) = |[f (1.7V) − f (1.5V)] / f (1.5V)|
3. Load resistor R_L connected between outputs O1 and O2. If V_OUT is the voltage wave maximum value across the resistor, then R_out is given by:
R_out = (V_DD / V_OUT − 1) × R_L = (1.2(V) / V_OUT − 1) × 400(Ω)
4. The I_IH and I_IL ratings are for each input when short circuited to VDD or VSS. I_IL1 is the current when CDS is inactive (when CO4N output is HIGH).
