Three typical applications for clocking devices are communications, consumer products, and memory. For communication designs, the most important parameter considerations are high performance requirements such as very low jitter as well as differential inputs to support higher speeds. For consumer applications it is common to find designs requiring high frequency accuracy and requiring multiple frequencies. For memory designs, the major consideration is conforming to JEDEC standards and DDR requirements, as well as meeting the Jitter and timing requirements of the system.
