Any idea on what would be a preferred (stable) device for a 10 MHz phase detector? I know that many use the 4046 (which has amongst others an XOR intetgrated) but what are the exact pros and cons of the different approaches compared to a (example) SOT-23 type 74HCT1G86? 73s Achim, DH2VA

Assuming that both signals has good S/N ratio and suitable signal level and transient shapes. the 74HCT86 should be better than the old CMOS 4046. I would expect a PI-loop to be used. Better yeat is a SR-flip-flop which would give a working range of +/- 180 degrees rather than +/- 90 degrees. A 74HCT00 could realize one of those. Cheers, Magnus

Achim, The 74LV4046 from Texas Instruments is far superior to any of the earlier variants. It can accept much wider range of both amplitude & frequency to yield clean, fast and low jitter output.
