Ω

Chip output impedance is nominally 300Ω.

Differential to single-ended output conver-

sion to 75Ω is performed in a balun with a

2:1 turns ratio, corresponding to a 4:1 imped-

ance ratio.

Note 1: The enable time is determined by the value of the capacitor on pin 8 (RAMP). A higher capacitor value will

increase the enable time, but will reduce the transient voltage.
