Pin Configurable/Selectable Oscillators

Introduction

Pin-configurable/selectable oscillators, often shortened to Pin Oscillators (or POs) are mainly intended to compensate for changing environmental conditions as well as form, fit and function replacements. In many real world applications they offer design engineers advantages in design cost, end of life product obsolescence, noise reduction, EMI/RFI reduction and improved accuracy.

534AB000020DGR Application Field and Working Principle

The 534AB000020DGR is a high performance pin-configurable oscillator from Euroquartz, designed for use in a wide range of applications such as telecoms, computing and instrumentation electronics.The 534AB000020DGR is available as a low frequency (10 kHz - 32 MHz), TTL/CMOS output, up to 7th harmonic-suppression and SC-cut crystal options. It also features a built in eye diagram monitor.

The 534AB000020DGR is a fully programmable oscillator that adjusts its output frequency, output strength and jitter parameters to the environmental conditions and to the customer’s application. This is achieved by programming the oscillator with the help of three onboard dipswitches and one pull-up/pull-down resistor. The dipswitches can be used to select the output frequency, output strength and jitter parameters, while the pull-up/pull-down resistor is used to adjust the jitter parameters.

The 534AB000020DGR is also available with an integrated power-on reset function that assists in ensuring that the oscillator is always properly initialized and in a known state upon startup.

Performance Benefits

One of the main performance benefits of the 534AB000020DGR over fixed-frequency oscillators is its ability to provide reliable, accurate, and repeatable output frequency regardless of environmental conditions such as temperature and supply voltage. This is achieved by its integrated digital frequency compensation and feedback loop, which constantly adjusts the output frequency according to input parameters.

The 534AB000020DGR also provides excellent noise reduction and EMI/RFI reduction, as well as improved accuracy across the board due to its programmable frequency selection and wide range of output frequencies. This makes it a great choice for applications that require reliable and accurate performance over a wide range of environmental conditions.

Conclusion

The 534AB000020DGR is a high performance, pin-configurable oscillator that offers design engineers advantages in design cost, end of life product obsolescence, noise reduction, EMI/RFI reduction and improved accuracy. It is ideal for applications that require reliable and accurate performance over a wide range of environmental conditions, and is available with built-in features such as an eye diagram monitor and a power-on reset option.
