Note 1

Note 2

These parameters are guaranteed and 100% production tested

Note 3

Design limits are guaranteed (but not 100% production tested) These limits are not used to calculate outgoing quality levels

Note 4

When measuring video amplifier bandwidth or pulse rise and fall times a double sided full ground plane printed circuit board without socket is recommend-

ed Video Amplifier 10 MHz isolation test also requires this printed circuit board

Note 6

Note 7

Measure output levels of the other two undriven amplifiers relative to driven amplifier to determine channel separation Terminate the undriven amplifier

Note 8 D

Av track is a measure of the ability of any two amplifiers to track each other and quantifies the matching of the three attenuators It is the difference in
