SG-3050 Series 32.768kHz Oscillators


A total solution from Epson Toyocom that allows designers to use space more efficiently


Epson Toyocom's SG-3050 SeriesThe maximum dimensions of the SG-3050BC series oscillators from Epson Toyocom are just 2.2mm x 1.4mm x 1.0mm, representing a 70 percent smaller footprint and 75 percent less cubic volume than its SG-3030 series predecessor and helping electronic equipment manufacturers further downsize their products while boosting performance.

In today’s world, 32.768kHz crystal devices are as indispensable as clocks, microcontroller sub-clocks, and timer functions in a variety of applications, including compact portable consumer products such as cell phones and digital still cameras. They are also essential for industrial measuring instruments and machine tolls as well as in-vehicle systems such as navigation systems, GPS modules, and engine control units. Moreover, 32.768kHz reference clocks are combined with 32.768kHz tuning fork crystal units and oscillation circuits for use in a single package.

Equipped with an ultra-compact QMEMS crystal chip, the SG-3050BC is one of the world’s smallest 32.768kHz crystal oscillators with a built-in crystal unit. Epson Toyocom was able to shrink the size of this oscillator by using a new structure that applies its original NPO structure wherein a crystal unit in a ceramic package is sealed together with an oscillations 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. These crystal oscillators will also pay dividends in the form of greater system reliability and quality, since the crystal unit’s characteristics will be assured prior to shipment, alleviating the need for customers to design oscillation circuits or adjust output frequencies. Epson Toyocom’s SG-3050BC is a total solution that will help customers add value to their systems by allowing them to use space more efficiently in feature-rich electronic equipment. Datasheet
