High-sensitivity AT crystal unit

Paul Boughton

Epson Toyocom Corporation, a leader in quartz crystal devices, has announced the development of the FA-20H, a 2.5 x 2.0 mm, high-stability, high-sensitivity AT crystal unit.

A microminiature surface-mount crystal unit whose small size was enabled by Epson Toyocom's proprietary microprocessing technology for miniature crystal chips, the FA-20H nevertheless features a low CI (equivalent series impedance) value in the low frequency band.

It also has more than sufficient stability and sensitivity to enable its use in reference clock applications for mobile handsets. Epson Toyocom intends to expand sales by positioning the FA-20H as its flagship crystal unit in the 2.5 x 2.0 mm size range.

The device is designed primarily for applications including mobile handset reference clocks, as well as a variety of clock applications for Bluetooth and terrestrial digital TV modules, wireless-LAN, UWB, and more.
