One would perhaps conclude that crystal oscillators
have lost their place in the hierarchy of standards, but this is far from reality.

Tanaka Kikinzoku Kogyo will supply these 1210-size AuSn alloy lids to crystal oscillator
manufacturers in Japan and overseas, and is aiming for 30 million yen in monthly sales as processing fee when mass production in 2014.
As the demand for very small crystal oscillators
has grown, it hasn't been possible simply to scale down existing designs.
In this mode, the DPLL output frequency will be based on crystal oscillators
used as the DPLL master clock.
has revised upward its shipments of crystal oscillators
for August to 10 million units, up from originally planned 6 million units, mostly thanks to huge added orders from supply chains of iPhone 5s.
Fox Electronics (Fort Myers, FL) has expanded its line of XpressO configurable crystal oscillators
with an extended temperature version of its 3.3 V HCMOS oscillator.
Xpress0 crystal oscillators
use a family of proprietary application specific integrated circuits (ASICs), designed and developed with a focus on noise reduction.
Faced with these concerns and growing demand - in 2007 more than an estimated 10 billion quartz crystals and oscillators were manufactured- the electronics industry has funded MEMS resonator research for more than four decades with the hope of developing frequency control products that in some applications could replace quartz crystal oscillators
without sacrificing quality or performance.
The state-of-the-art McQ 512 Trimmer is perfect for an endless variety of applications that require miniaturized capacitance trimming, including avionics apparatus, communications equipment, oscilloscopes, crystal oscillators
and crystal filters.
SMD temperature compensated crystal oscillators
(TCXO) series NT3225 are available.
Fox Electronics is a private company based in Florida, which provides frequency control solutions that include the XpressO family of revolutionary quick-turn oscillator products, quartz crystals and voltage-controlled crystal oscillators
. Its revenue was approximately USD23m in calendar year 2011 and the company has continued to be profitable.
