HFF crystal units

HFF crystal unit / HFF crystal oscillator (high-frequency fundamental)

In order to increase the frequency of oscillators, it is necessary to make the chip thinner, but conventional processing methods imposed limitations on producing thin chips.

A high-frequency fundamental was enabled without compromising crystal chip strength by photolithographically processing only the oscillating portion of the chip so as to form an extremely thin inverted-mesa structure having a thickness of only several microns.

Advantage of high frequency oscillation at the fundamental frequency

High-frequency fundamental oscillation helps stabilize high-speed, high-volume data transmissions because nearby high-frequency components can be suppressed.
