ABSOLUTE MAXIMUM RATINGS

ELECTRICAL CHARACTERISTICS

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional

operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to

absolute maximum rating conditions for extended periods may affect device reliability.

Note 1: Input is a square wave with 0.5GHz frequency and <200ps rise time.

Note 2: External capacitance on the input

≤ 0.4pF.

Note 3: Pulse-width distortion measured at the 50% level of the output pulses: Input is 900µA, zero-peak.

Note 4: Output noise is measured through a four-pole Bessel filter with -3dB bandwidth of 800MHz.

Noise is then referred to the input by dividing the DC transimpedance.
