Product Summary
The ics342m-12lf is a low cost, dual-output, field programmable clock synthesizer. The ics342m-12lf can generate two output frequencies from 250 kHz to 200 MHz, using up to two independently configurable PLLs. The outputs of the ics342m-12lf may employ Spread Spectrum techniques to reduce system electro-magnetic interference (EMI).
