![]() ![]() Unlike oscillators using crystals, the LTC1799 has infinite frequency resolution the output frequency can be set to any value in the 5kHz to 20MHz range. ![]() Its stingy temperature and voltage coefficients (typically ☐.004%/☌ and 0.05%/V, respectively) maintain accuracy over all operating conditions. ![]() With a frequency tolerance 0.5% typical and 1.5% worst-case, the performance of the LTC1799 is similar to that of ceramic resonators and vastly superior to oscillators that use discrete resistors and capacitors. LTC1799: Advantages in Precision, Resolution and Size Figure 1 shows a circuit that generates a precision 5MHz signal. It typically draws 1mA of supply current. The LTC1799 operates over a 2.7V to 5.5V supply range, with a voltage coefficient of 0.05%/V. A proprietary feedback loop maintains this accurate relationship over all operating conditions, providing a temperature coefficient that is typically less than ☐.004%/☌. Where N is the on-chip divider setting of 1, 10 or 100, depending on the state of the DIV pin. Selecting the proper resistor is straightforward because the LTC1799 follows a simple relationship between R SET and frequency: A programmable on-chip frequency divider divides the frequency by 1, 10 or 100, extending the frequency range to greater than three decades (5kHz to 20MHz).įigure 1. The LTC1799’s internal master oscillator is a resistance to frequency converter with an output range of 500kHz to 20MHz. With a 0.1% resistor, the frequency accuracy is typically better than ☐.6%. A complete oscillator circuit requires only an LTC1799, a frequency-setting resistor (R SET) and a bypass capacitor, as illustrated in Figure 1. The LTC1799 is the only oscillator IC that can accurately generate a square wave signal at any frequency from 5kHz to 20MHz without the use of a crystal, ceramic element or existing clock reference. The LTC1799 offers an alternative that combines the frequency stability and accuracy of a ceramic resonator with the flexibility and ease of use of an RC oscillator, while requiring less space than either. #Osculator for ceramic resonator Pc#Generating various frequencies from a single crystal or ceramic oscillator requires additional circuitry that will add to the component list and consume PC board space. These circuits are also bulky, sensitive to acceleration forces and tend to be less robust than RC oscillators. Very accurate oscillators with a predetermined frequency may be realized using either crystals or ceramic resonators as stable frequency elements crystal oscillators offer the highest performance, although they are costly. These solutions are bulky and inaccurate, especially at frequencies above a few hundred kilohertz. Low cost RC oscillators can be built using discrete components such as comparators, resistors and capacitors, or by using simple integrated circuits such as the industry-standard 555 timer in conjunction with several discrete components. Generating a periodic waveform of arbitrary frequency is not always a trivial task.
