The LMK00334RTVTQ1 is a fully integrated, voltage-controlled temperature compensated crystal oscillator (VCTCXO) from Texas Instruments. It is perfect for products that require high frequency timing stability across varying temperature and voltage conditions. It is a cost-efficient alternative to all-silicon timing solutions and comes with a wide range of frequency and output stability options to accommodate a variety of system requirements.

The LMK00334RTVTQ1 is designed for any application that needs frequency and/or timing stability over a broad temperature- or voltage range. It offers a user-friendly solution to maintain the accuracy of sophisticated systems while keeping cost, size, and power consumption to a minimum. Examples include key markets such as medical, defense, and industrial instrumentation, which demand precise and reliable operation. In addition, due to its wide frequency range and output stability options, the LMK00334RTVTQ1 can also be used for frequency synthesis and wireless communication systems.

The LMK00334RTVTQ1 is ideal for applications that require a reliable and accurate frequency reference. It features a low noise fanout buffer and an integrated voltage-controlled temperature compensation circuit that can provide a stable and precise output frequency over a wide input voltage and temperature range. It also has an integrated low drift voltage regulator and on-chip 100 Ωxtal termination resistor. This ensures excellent frequency stability in multiclock designs, such as digital systems, as well as excellent rejection of external supply noise.

The LMK00334RTVTQ1 works by using a quartz crystal as the frequency reference. An internal oscillator circuit is used to generate a clock signal with a frequency proportional to the loaded quartz crystal. The output frequency of the internal oscillator is then compared to the initial frequency of the quartz crystal, and a correction voltage is applied to adjust it as needed. The voltage-controlled temperature compensation circuit then adjusts the output frequency according to the external temperature. This allows the LMK00334RTVTQ1 to maintain a very stable and accurate output frequency regardless of temperature or input voltage variations.

The LMK00334RTVTQ1 is designed to meet the stringent performance requirements of a variety of systems. It offers a wide frequency range (1.7 MHz to 50 MHz) and output stability options (±0.1 ppm to ±50 ppm). It also includes power supply and ESD protection, as well as a wide input voltage range (2.5 V to 3.6 V). Additionally, it requires only a minimum of external components, allowing for easy integration into an existing system. All of these features make the LMK00334RTVTQ1 an ideal solution for any application that requires reliable frequency and/or timing stability over a broad temperature- or voltage range.
