Oscillators The TD-14.7456MCE-T is a crystal oscillator device typically used in various radio frequency (RF) applications for sustaining frequencies up to 1.4 GHz. It is based on a low voltage positive-resistance full bridge circuit which works as a high frequency oscillator. It provides reliable frequency stability and the ability to spread its signal over relatively long distances. ApplicationsThe TD-14.7456MCE-T is often employed in radio frequency (RF) communication systems such as in radio receivers, television receivers, radio transmitters, and other electronic communication equipment. Additionally, it can be used in wireless networks and remote control systems. As a crystal oscillator device, it is also often used in frequency generation, precision timing devices, and instrumentation applications. Working principleThe TD-14.7456MCE-T uses a low voltage positive-resistance full bridge circuit in order to generate oscillations up to 1.4 GHz. The bridge is made of four transistors which drive a pair of anti-parallel diode junction networks. When power is connected to the bridge, a recombination of charge carriers takes place at the diode junction networks which leads to the commencement of current oscillations. The current waveform is transferred to the LC tank circuits for the subsequent generation of radio frequency output. The frequency generated depends on the choice of the LC circuit. By altering the capacitance and inductance values in the LC circuit, different output signals can be achieved.Output characteristicsThe TD-14.7456MCE-T has a maximum rated output power of 10.1 dBm with a power coefficient linearity of 1.5 dB/V in the range of 1 to 5.67 volts. It has a minimum harmonic distortion of -120 dBc/Hz with a maximum harmonic distortion of -100 dBc/Hz. Its output impedance is 75 ohms and it typically has a phase noise of -106 dBc/Hz. It has an output voltage of 1.5 to 5.67 volts, an output load capacitance of 3 pF to 6 pF, and a center frequency of 14.7456 MHz.
