Epson Toyocom Corporation’s U.S.-based Timing Products Division has announced the development
and availability of the world's smallest 32.768-kHz crystal oscillator. The maximum dimensions of the new crystal oscillator, SG-3050BC, are only 2.2 mm x 1.4 mm x 1.0t mm.
With a footprint and cubic volume that are 70% and 75% smaller, respectively, than its predecessor, the new crystal oscillator allows electronic equipment manufacturers to not only downsize their products but also boost their performance.
Samples of the new SG-3050BC are available and priced under $10 per unit.
The SG-3050BC, equipped with an ultra-compact QMEMS

crystal chip, is the world's smallest 32.768-kHz crystal oscillator with built-in crystal unit.
Epson Toyocom reduced the size of this oscillator by using its own NPO (New Platform Oscillator) structure

, wherein a crystal unit in a ceramic package is sealed together with an oscillation circuit in a molded plastic housing.
Combining a compact crystal unit with an oscillation circuit rather than providing them separately, significantly shrinks the space required.
The crystal oscillators also pay dividends in the form of greater system reliability and quality, since the crystal unit's characteristics are assured prior to shipment, alleviating the need for users to design oscillation circuits or adjust output freque
ncies.
The SG-3050BC also outperforms the previous SG-3030 series, boasting an operating voltage range of 1.2 to 5.5 V and initial frequency tolerance of 5.0 ± 5.0 × 10

.
In recent years, heightened awareness of the need to reduce environmental impacts has been driving demand for ever more compact electronic devices that maintain greater functionality while consuming fewer raw materials and less power.
As tuning-fork crystal units and oscillation circuits become smaller it is becoming increasingly difficult to design combinations with equal or superior stability and power consumption compared to their predecessors.
Epson Toyocom has responded by developing the ultra-compact 32.768-kHz SG-3050BC crystal oscillator.
Epson Toyocom had previously released ultra-compact 32.768-kHz tuning-fork crystal units and has even established services to support oscillation circuit design, such as

).
Now, with the addition of the SG-3050BC to the lineup, Epson Toyocom offers comprehensive solutions for both ultra-compact crystal units and oscillators.
