HCMOS 3.2 x 2.5mm 3.3V Oscillator

Fox Electronics, a leading global supplier of frequency control solutions, recently released a new HCMOS in a compact 3.2 x 2.5mm 3.3V Oscillator for Ethernet applications.Here they offer wide range of crystal oscillator. In their line items they have introduced XpressO HCMOS oscillators. FXO-HC33 series has its special specification as a 3.3 volt and the dimensions are 3.2 mm x 2.5 mm package oscillators, and its stabilities is ±25 ppm with frequency range of 0.75 MHz to 250 MHz.

This oscillator has operation ability in temperature range of -20°C to +70°C or -40°C to +85°C. This oscillator is come with many features as Frequency Resolution to six decimal, tri state enable/disable feature, fully RoHS and REACH (Registration, Evaluation, Authorization, and Restriction of Chemicals) compliance. This XpressO HCMOS oscillators used in different applications like SONET, Ethernet, Storage Area network, test and measurement equipment and also for any application which requires oscillator. This Fox Oscillator is designed and developed with focus on noise reduction technologies.

Delta Sigma Modulator reduces noise to the levels that are comparable to other traditional Quartz and SAW oscillators. This XpressO HCMOS is Gold over Nickel Termination Finish provides the best conductivity which results in best performance of the application. By its low cost and extremely low jitter it becomes the best suited oscillator for the applications.

These XpressO HCMOS are ready to ship and samples are also available.

Equivalent Circuit

An equivalent circuit refers to a theoretical circuit that maintains all of the electrical characteristics of a given circuit. It proves to be quite useful for making quantitative predictions about the behavior of the induction machine, under various operating conditions. Usually, an equivalent circuit is required to simplify more complex circuit in order to aid analysis. Usually equivalent circuits consist of linear elements; however complex circuits have non linear behavior.

The equivalent circuit shown above depicts electrical activity of a quartz crystal unit operating at its natural resonant frequency. The C_O, or shunt capacitance, represents the capacitance of the crystal electrodes plus the capacitance of the holder and leads. R₁, C₁, and L₁ compose the "motional arm" of the crystal, and are referred to as the motional parameters. The motional inductance (L₁) represents the vibrating mass of the crystal unit. The motional capacitance (C₁) represents the elasticity of the quartz, and the resistance (R₁), represents bulk losses occurring within the quartz.
