Part No : AD8145
Application :Converting R,G,B Differential video into single ended R,G,B video
Question : How to Calculate Rs and cutoff frequency at input side of AD8145 if i am using 3 positive clamp and 3 negative clamp diodes(1N4448) and Differential input termination Resistor RT = 120 ohms (Datasheet of AD8145, Page No 17 ,Figure 40. Using Two 1N4448 Diodes in Series as a Clamp) ?
How to calculate Rs if i have to use 3 positive clamp and 3 negative clamp diodes(1N4448) in AD8145.
Note that i am using 120 ohms as a differential termination(RT) resistor and I want 40MHz band width in front end of AD8145 and also provide the calculation for bandwidth and Rs calculations.
