For low-noise VCOs & PLLs

Quartz oscillators are the way to go when you need a precise, stable frequency source but what do you do when an application calls for a non-standard frequency? Custom-made crystals are an expensive option but now Cypress has come up with a cheaper alternative...The buzzword is CyberClock and describes a relatively new technology in the field of clock generators for use in complex systems like PC motherboards. If you take a look at an old motherboard it is easy to spot the crystal generators dotted around the board providing all the different clock sources. More modern systems are increasingly employing just a single clock generator and deriving all the other signals from this one source.
