Crystal Units

♦ Crystal unit is a passive component using piezoelectrical effect of the crystal. By applying the voltage, transformation occurs in the crystal and it oscillates frequency of high-stability with the natural resonant frequency of vibration.

Crystal Clock Oscillators

♦ Clock Oscillator is applicable to clock use and small size crystal oscillator, a kind of SPXO (crystal oscillator simply combined with crystal unit and oscillation circuit). (Differential output products (e.g., PECL output or LVDS output) are introduced in the SPXO page.)

Automotive safety(ex.ASV) is introduced in this page too.

Standard Type | 32.768kHz (Low Current Consumption) | For Automotive Safety | 32.768kHz for Automotive Safety | High-precision Type | Low Phase Noise Type | Ultralow Power Type | Dual output (32.768kHz + MHz) | 5.0 × 3.2mm |

Simple Packaged Crystal Oscillators (SPXO)

♦ SPXO is the simplest Crystal Oscillator with no compensation or control of temperature made by combination of a crystal unit and oscillation circuit. SPXO, especially small products used for clock purpose, are introduced in the Crystal Clock Oscillator (CMOS output) page.

Temperature Compensated Crystal Oscillators (TCXO)

Temperature Compensated Crystal Oscillators (TCXO)

♦ TCXO is the Crystal Oscillator with good temperature characteristics of Crystal unit and opposite temperature characteristics circuit (temperature compensation circuit) across a wide temperature range.
