I need to control the cutoff frequency for several LP filters independently. Their cutoff frequency 1/100th of the input clock frequency. I need to try and find an oscillator/clock generator (preferably multiple clock signals in a single IC) that can go 100Hz and up (with max of 500kHz, but this maximum can be much MUCH MUCH MUCH lower). It needs to be programmable without external resistors or capacitors (I need the MCU to be able to control the frequency).
Anyone know of such a software-programmable low-frequency multiple-clock generator?
