The VCLFO 10 is a simple-to-use 0-5V voltage-controlled LFO chip with many more features than your average LFO.It can produce 16 different waveforms in two banks of eight, including a wandering random wave and a noise source. Waveforms can be further shaped by the Wave Distort feature.
There is an optional sample-and-hold module that can sample whatever is selected, the current waveform or the noise or random source. The LFO frequency, waveform selection, waveform distortion, S&H rate and output level are all voltage-controlled using 0-5V.
This chip is an upgraded (but still compatible) version of the original VCLFO 9D chip. It offers an improved sample rate (31.25KHz instead of 19.5KHz), better waveform storage resolution (16-bit instead of 8) and no longer requires use of a timing crystal. Additionally, it is now possible to configure the chip for inverted CV inputs, which makes dealing with CV mixers very simple.
Another new feature is the optional on-chip waveform smoothing filter, which is designed to remove clicks caused by feedthrough in application circuits like tremolos.Download Electric Druid VCLFO10 Datasheet
