Crystal Companies

Bomar Crystal Company produces Temperature Compensated Crystal Oscillator TCXO and VCTCXO with a wide range of output options, low jitter and are available in HCMOS or Clipped Sine wave (S/B low jitter and available in HCMOS or Clipped Sine wave). Tolerance to ±0.5ppm with temperatures to -45^o to +85^oC. Packages include Thru Hole (Full and Half Size), Metal SMD in Gull Wing or 11.4x9.6mm or Ceramic SMD.

VCXO Voltage Controlled Crystal Oscillators - Bomar VCXO's are available in thru hole and many sizes of SMD packages. They offer wide frequency ranges and voltages of 5.0vdc, 3.3vdc, 2.5vdc and 1.8vdc. Tri-State E/D is optional and offer many options for pull range.

OCXO - Bomar Crystal is able to offer a full line of ultra low tolerance OCXO (Oven Controlled Crystal Oscillators), OCXO’s for applications where frequency tolerance and stability are critical like Satellite Radios, Sonet Clocks, Synthesizers, Instrumentation and GSM Base Stations.

VCTCXO, OCXO, TCXO Oscillators all have something in common. What is a TCXO? When would someone need a TCXO or a VCXO? TCXO is an acronym for temperature compensated crystal oscillator. Typically a TCXO employs a thermistor network to generate a correction voltage, which reduces the frequency variation over temperature. TCXO, VCXO, VCTCXO, OCXO, SMD Crystals, and a TCXO oscillator all have crystals in them. SMD crystals can be found in a VCXO, TCXO, OCXO, VCTCXO, and a TCXO oscillators. SMD crystals help the basic functions of all the above mentioned oscillators, and each of those oscillators have daily applications in everyday life.

What does VCXO stand for? VCXO is short for voltage controlled crystal oscillator, and it is usually used to control the frequency of operation, which are needed to be adjusted only finely. The crystals in the VCXO allows for the fine tuning. VCXO are used in various applications, such as digital TV, and digital audio. A VCXO is different than an OCXO, which stands for oven controlled crystal oscillator. An OCXO is different in its application function, and as such is used in different products. The crystal in OCXO helps to keep frequency consistent and stable, especially in radio transmitters, cellular base stations, military communications equipment, and for precision frequency measurement. A VCXO deals with frequency, where as a VCTCXO and TCXO both deal with temperature. A VCTCXO is a Voltage Controlled Temperature Compensated Crystal Oscillator.

SMD crystals are important, because they help with the basic function of many machines—including VCXO, TCXO, OCXO, VCTCXO, and TCXO oscillator. If you are shopping for any of these items then you should make sure you go to someone who knows how to make these items properly. They take care of such an important function that if they were to fail then the entire function would fail with it. Each of these items is used to work some very used items in our lives, including radio and refrigeration.
