Parts are available with internal trimmer options and clipped sine / sine and square wave outputs. The devices offer good reliability at a low cost and, whilst primarily developed for Telecommunications Applications, they are also very suitable for many other Networking, Set Top Box, Phase Locked Loops, Video Game & many Consumer Applications.
