Parts are available with internal trimmer options and clipped sine / sine and square wave outputs. The devices offer good reliability and, whilst primarily developed for Telecommunications Applications, they have been found to be very suitable for many other Networking, Ethernet, Audio & Modem Clocks, Set Top Boxes, Phase Locked Loops, Video Games & many Consumer Applications.
