Epson Toyocom Commercializes Compact, High Accuracy Crystal Oscillators
- New SG-211S*E series supports low voltage, high temperature applications -
Epson Toyocom Corporation, the leader in crystal devices, has announced the commercial development and volume production of the new “SG-211S*E” series of compact, highly accurate simple clock oscillators (SPXO). The new crystal oscillators support voltages as low as 1.8 V and temperatures as high as 90 ℃.
Epson Toyocom has long sold compact and highly accurate SPXO for use as reference clocks in wireless networks, Bluetooth, and other near field communication applications.
Demand for smaller wireless devices is on the rise, as are the temperatures of components contained in compact housings. This, along with strong demand for low voltages to maximize battery run time, indicates a clear need for devices that support high temperatures and low voltages.
To meet these market needs, Epson Toyocom upgraded its already compact and highly accurate crystal oscillators with support for voltages as low as 1.8 V and a frequency tolerance of ±15 × 10-6 at temperatures up to 90 ℃.
The SG-211S*E series also has 5 dB (detuning frequency: 1 kHz) lower phase noise(*1) than earlier products, making it an excellent choice for the low phase noise requirements of reference clocks in wireless communication.

(*1) Phase noise
Energy that is radiated near the oscillation frequency, and that occurs due to the internal and external environmental factors (noise) of a crystal oscillation circuit. Wireless signal transmission errors can occur when this noise value is too high.
