Test levels: (A) 100% tested at +25°C. Over temperature limits set by characterization and simulation. (B) Limits set by characterization

and simulation only. (C) Typical value only for information.

(2)

3.3-V supply filter specifications are ensured by 100% testing at a 5-V supply with design and characterization.

(3)

Return loss is calculated assuming an ideal 75-

Ω external series resistor along with the THS7376 channel output impedance into an

ideal 75-

Ω end-termination resistance.
