Single-ended LVPECL to single-ended LVTTL 1

[snapshotguru]

I have a single-ended LVPECL output that I need to convert to a single-ended LVTTL output. I know they make single-ended LVPECL to differential LVPECL translators (second step is to connect this to a differential LVPECL to single-ended LVTTL translator), but I want to skip this step and use a differential LVPECL to single-ended LVTTL translator. Can I connect the single-ended LVPECL output to the P-side input and tie the N-side input to ground of the differential LVPECL to single-ended LVTTL translator?

Do you even know the output voltage levels of PECL?

Depending on the data rate, perhaps an ultra fast comparator like an AD ADCMP601.

If you want to go single ended LVPECL to single ended LVTTL, I would run the LVPECL through a comparator. Tie Vcc to 3.3V, Vee to 0V, the signal to V+, and a 2V reference to V-. The output should be LVTTL.

Why not just use a commercial LVPECL to LVTTL converter?
