Then, turning the “tone” knob up introduced asymmetry to the triangle wave and turning the “distortion” knob up caused a “shark fin-like” edge to appear at the leading edges of each half-cycle. The Fulltone OCD clone in action. Websine wave signal as clock input In this particular design, I have a 10 MHz sine wave (from an atomic clock source) as my clock input to my Virtex 5. It's been working pretty well. The sine wave has a 1.4 V peak to peak and is centered around 1.2 V (e.g. it swings from 0.5V to 1.9V). I set the I/O standard for this input to be LVCMOS25.

WebOften, the output of a sinewave source is specified in dBm, which is a power output. This can be converted to a voltage swing if the impedance of the operating environment is known. … Webwave form looks more like a square wave than a sine wave. Distortion is a direct result of excess gain overdriving the amplifier; thus, gain must be carefully controlled in low-distortion oscillators. Phase-shift oscillators have distortion, but they achieve low-distortion output voltages because cascaded RC sections act as distortion filters.
