Clock generation requirements for applications such as routers, servers, networking switches, and line cards continue to demand increased frequency, better signal purity and higher component reliability. Systems are getting more complex with additional new features requiring many different frequencies. Traditionally clock generation for markets such as High Definition Video (HDV) processing, high-end computing, networking / telecom, automatic test equipment and industrial applications have been primarily serviced by 3rd overtone or SAW based crystal oscillators. These technologies have physical limitations making them time consuming, difficult and costly to manufacture for frequencies above 50 MHz.
This presentation will compare and contrast traditional 3rd overtone or SAW based crystal oscillator solutions with PLL base crystal oscillator modules as an alternative solution for clock generation implementations suitable for frequencies above 50 MHz.
