Pin Configurable/Selectable Oscillators

Pin configurable/selectable oscillators are frequency and time-base devices used in a wide range of applications, such as telecommunications, automotive, industrial controls, and computer peripherals. The 516FEA000270BAG is a precision surface-mount quartz crystal clock source designed for a variety of applications.

Application Field and Working Principle

The 516FEA000270BAG is applicable in 3V to 3.6V environments. It has a low power consumption of 0.68mA when operating off of a 3.3V power supply, and a maximum current draw of 0.76mA when running off of a 3.6V supply. This component offers frequency-range flexibility, with both a low frequency of 0.5MHz and a high frequency of 32MHz available. It can operate on a wide temperature range from -40°C to +85°C and includes a clock enable/disable and output-mode control interface.

The 516FEA000270BAG employs a voltage-controlled crystal oscillator (VCXO) architecture that integrates a complementary noise-canceling circuit to achieve high accuracy. This device uses a quartz crystal oscillator to convert an AC waveform at a specific frequency into a pulsed voltage waveform, which in turn is sent to an oscillator circuit on the output. The crystals used in the device are very stable, maintaining accuracy and reliability cycle to cycle. In addition, they require minimal temperature compensation while providing little power consumption.

The device also has a built-in self-programmable frequency synthesizer. The frequency of the output is controlled by an external voltage input, which is then programmed by a programmable logic array (PLA) on the integrated circuit. The user can then customize the configuration of the oscillator to specific frequencies. The frequency output from the 516FEA000270BAG can also be manually adjusted, providing additional versatility.

Performance Characteristics

The 516FEA000270BAG exhibits outstanding performance in terms of time-based repetitive accuracy, which is ensured by its advanced phase-locked loop (PLL). The device has a frequency tolerance of ±20ppm over a wide temperature range and a stable output over the entire operating range of -40°C to +85°C. An internal divider further allows divisions of its base frequency to act as a clock source of smaller division ratios.

The 516FEA000270BAG has an exceptionally low power consumption and is rated at 0.68mA, making it easy to integrate into systems that need to meet stringent power requirements. It also provides a high output level of 10KV/V for precise signal regulation in a wide range of applications.

The device\'s power-management features include a high-efficiency output-signal signal path, programmable multi-level logic output, and a low-noise signal path. It boasts consistent, reliable performance across its entire operating range over a wide temperature range. Additionally, its low voltage supply range allows easy integration into existing systems.
