ADCMP600 used for 10 MHZ Sine to Square Wave Conversion

Hi!

Figure 22 in the ADCMP600 data sheet shows a "Self-Biased 50% Slicer" circuit.   Is this circuit suitable for converting a 10 MHZ Sine

to Square Wave.

Input Signal can range from 0 dBm (0.6V pk-pk) to 15 dBm (3.5 V pk-pk)...Input signal is AC Coupled.

Thanks,

Ed

  • Hi Ed-

    The application engineer for this part provided me with the following response to your question.  I hope this is helpful.

    The Slicer circuit in the datasheet works for non AC coupled inputs.  It averages out a dc value of the input waveform and applies it as a threshold.


    The  AC coupled signal will exceed the ADCMP600 negative input voltage range of -0.2V.   The CMP401 may be an option.  With the dual supplies, the ‘Vp pin input voltage  range will handle the AC coupled input signal , and the Vn pin can be tied to ground.   Also maybe the AD8561, although it is only specified  with a input voltage range of -5 to 3V.
