Pin Configurable/Selectable Oscillators are practical and useful solutions for embedded mode applications due to their power and flexibility in terms of output clock frequency selection and expandability. The common option to select an output frequency is through the use of solderable jumpers, however, newer Oscillators such as the 513FBA000576BAGR allow for frequency selection through the use of two or three pins on the Oscillator.

The 513FBA000576BAGR is a Pin Configurable/Selectable Oscillator containing an external local oscillator (XLO) pin, which is programmed by the user to determine the output frequency. With the combined use of the separated drive and XLO pins, users can configure the Oscillator to produce a wide range of output frequencies up to 150MHz. This Oscillator is ideal for designers who have applications requiring a higher frequency output.

The 513FBA000576BAGR is based on the BLOCK Solex oscillator technique. The basic principle behind BLOCK Solex is that the oscillator sets the frequency by the balance between pull-up forces and pull-down forces. This is achieved by controlling the transistors in the north-bridge and south-bridge, thus changing the oscillator’s frequency. The drive and XLO pins are used to access the input and output of these two transistors, respectively. The drive pin sends an external signal or voltage to each of the transistors, determining the oscillator pulse width.

The 513FBA000576BAGR is designed to work with voltage levels from 1.4V to 4.9V and is available in industrial and automotive-grade packages. Its quick response time and low start-up current can meet the power requirements of almost any embedded system. The frequency accuracy of this Oscillator is also specified at ±25 ppm to ensure time-accurate operation across all frequencies.

The 513FBA000576BAGR Pin Configurable/Selectable Oscillator is ideal for power-sensitive embedded applications requiring a highly-accurate, low-power Oscillator. With its external local oscillator pin and its wide range of frequencies available, plus its low power draw and quick response time, it is highly recommended for embedded applications requiring higher clock frequencies.
