According to the datasheet of MAX2606, Absolute maximum rating for OUT+, OUT- to GND -0.3V to (Vcc+0.6V). And Vout (p-p) (differential) = 2x1mA[(1kΩxRload)/(1kΩ+Rload) I implemented the following circuit (both C2 and C3 are 2.2nF and other values are same as in the diagram) and get the single ended output and measured using the oscilloscope. Unfortunately the output peak to peak voltage is just 300mV. (Vcc = 4.5V) Why I can't get at output peak to peak voltage least up to 2.5V? Please help me, I want to input the output of this to a 74F14 schmmit trigger IC. Any suggestions please?
