Speaker Biography:
Brian Drost received the B.S. degree in electrical and electronics engineering in 2009 and the M.S. degree in electrical and computer engineering in 2011, both from Oregon State University. He is currently employed by Silicon Laboratories (2011 - present) where he is working on clock references and oscillators.
Abstract:
One or more clocks are required in nearly every electronic system. Across
applications such as microprocessors, audio and video, and wireless
communication, the noise, frequency, and power consumption requirements of
these clocks can vary dramatically. Modern electronic devices are combining
more features into a product than ever before, and with so many different
clocks required, generating them can become complicated and expensive.
Today, the vast majority of clocks are generated from quartz crystals
references. Although crystals provide both low phase noise and excellent
frequency stability, they must be precisely machined which places lower limits
on both their cost and flexibility. In this presentation, the conventional
methods of clock generation and their limitations will be discussed followed by
an introduction to some of the innovations Silicon Labs has brought to the
timing market. This includes both products that use quartz crystals and those
that replace them. These devices both increase performance while reducing
complexity and cost.
