THS4524-EP Crosstalk Specification?

Other Parts Discussed in Thread: THS4524-EP, THS4524

Hey,

Does anybody happen to know the channel-to-channel crosstalk specification of the THS4524 or THS4524-EP at 20MHz? The datasheets only seem to specify it up to 200kHz.

Thanks

    Hello IDK,

    From figure 41 and Figure 22 you can see that the amplifier loop gain is proportional to frequency.  From this you can extrapolate the cross-talk curve out to 20MHz.  I am estimating that the 20MHz cross-talk would be -85dBc. 

    Keep in mind that cross-talk at higher frequencies will be determined by board layout.  Even though the amplifier cross-talk may be -85dBc, the board induced cross-talk may be much worse. 

    Regards,
