Pin Configurable/Selectable Oscillators (PCSOs) offer a wide range of benefits for applications that require a mix of design flexibility, multi-frequency performance and cost savings. Especially in consumer electronics, aerospace, military and telecom applications, the ability to easily customize the frequency and form factor of a component is essential. The 534PA000366DGR is a PCSO designed specifically to meet these demanding requirements.

The 534PA000366DGR features an integrated, highly configurable and selectable oscillator. It is part of a larger 534PA family of PCSOs from Microchip Technology Inc., which offer a variety of tunable functions including frequency range, start-up frequency, output frequency, voltage control, power supply and temperature range. The 534PA000366DGR provides convenience and customization of frequency and form factor, with six selectable oscillator frequencies of between 16kHz and 54MHz. The oscillator can be tailored to the exact needs of the application by changing the configuration of its 5 voltage-controlled pins (VCPs). Configuring the VCPs allows the user to select (or customize) the start-up frequency, output frequency, amount of frequency pull-in range, and power supply.

The 534PA000366DGR’s frequency range and VCP flexibility also provide design engineers with scalability and tuning options. Scaling is enabled via VCPs, while tuning can be adjusted by varying the symmetry of the VCP voltages. The 534PA000366DGR is especially useful for applications requiring an extra degree of fine tuning. With its pin-programmable, user-selectable design, the PCSO can be adjusted for multiple frequencies or even implement frequency delta when desired.

Due to its low start-up power consumption, the 534PA000366DGR is especially suitable for energy-sensitive applications in harsh environmental conditions. The device is built with very robust power switching, reverse polarity and short-circuit protection, and can work reliably in temperatures ranging from -40 to +105°C.

The 534PA000366DGR supports a wide range of frequencies and is capable of operating at 54MHz. It is packaged on a small 5mm x5mm QFN package and therefore ideal for applications where space is limited. The device provides an extremely high frequency stability of ± 20 ppm over the extended temperature and supply range, making it ideal for use in very sensitive applications.

A major benefit of the 534PA000366DGR is its flexibility. All the required components, such as filters, voltage monitors, rejectors and pull-down resistors, are integrated on-chip and can be easily configured via the VCPs. With just the right configuration, the user can achieve both the desired temperatures and frequency range. The 5-pin VCP logic is user friendly and easy to implement, giving designers the freedom to tailor the PCSO to their exact needs and preferences.

The 534PA000366DGR is a versatile, pin configurable/selectable oscillator from Microchip Technologies Inc. that offers a wide range of features and benefits. Its six selectable oscillator frequencies, VCP flexibility, scalability, and design freedom make it a great choice for high-performance applications in telecommunications, consumer electronics, aerospace, and other markets.
