Other Parts Discussed in Thread: SN74LVC1G17, SN74LVC2G17, SN74AUC1G80, SN74LVC1G80
I have two pulsatile signals whose frequency I wish to divide:
A. 8x frequency division of a pulsatile 80 MHz input. As exemplified in the following oscilloscope screenshots, its waveform is somewhat irregular, with a primary ~3 dBm peak followed by a secondary peak that can be up to -4.5 dBm high, in its average power (all measured to 50 ohm load):
B. 16x frequency division of a pulsatile 160 MHz input. As exemplified in the following oscilloscope screenshot, its waveform is clean but rather weak (-19.8 dBm in its average power to 50 ohm load, if I've calculated correctly):
In both cases, the optimal output would be a ~10 MHz sinusoidal, or clipped-sinusoidal wave, at ~3.3 Vpp to a DC-blocked 50 ohm load. Other periodic ~10 MHz output signals may also be acceptable, if they satisfy VOH of at-least 2 Volts and VOL of at-most 0.4 Volts, to a DC-blocked 50 ohm load.
Browsing through the available frequency dividers at this category, I could not identify a part that is supposed to work at this bandwidth, let alone with pulsatile input signals. Can you please suggest which evaluation board of yours, or a cascade of evaluation boards, is most likely to be able to pick up these signals correctly and produce the required output? Should I first regularize the input signals to square waves using a flip-flop (thereby also simplifying the problem to 4x/8x division of the resulting 40 MHz/80 MHz square waves)? If so, which flip-flops would be optimal for these input signals?
Thanks a lot,
