Pin Configurable/Selectable Oscillators are high-performance oscillator solutions with a wide variety of output frequency, pullability and jitter characteristics to meet the most demanding application requirements. The 532BC000566DGR oscillator is one such device, with a frequency range of 10 kHz to 300 MHz and a jitter of less than 15 ps.

The main feature of the 532BC series is its ability to be configured or selected using the pins. The 3-pin version offers the most flexibility, allowing users to access optional functions such as different frequency multiplication, output enable, pullability and power down, depending on the needs of the application. These options are selected by the end user via on-chip resistors, giving them the flexibility to tailor the oscillator for a particular application.

The 532BC series also provides low jitter specifications. Its phase noise is low enough to ensure its communications applications meet stringent timing requirements, yet it typically consumes only 250 mW of power.

Regarding its working principle, the 532BC oscillator family is based on the Pierce principle, a well-established oscillator topology that has been used in oscillator designs for decades. It consists of an amplifier with negative feedback, typically connected to an external series inductor or tank circuit, which forms a resonator.

When the circuit is powered up, the signal generated at the amplifier is sent to the tank circuit, where it is amplified until it is large enough to meet the exit threshold of the amplifier, causing the signal to be inverted and sent back to the amplifier. This is repeated and eventually the signal will become a stable oscillation at the resonant frequency of the tank circuit.

The frequency of the oscillation is set by the external tank circuit, which can be tuned to the desired frequency by adjusting an on-chip resistor. This can provide open-based tuning across the full frequency range of the oscillator.

The 532BC series oscillator also uses clock generation technology to further improve the phase noise and jitter performance. This is achieved through on-chip digital logic and delay lines to generate a stable clock signal with minimal jitter.

The 532BC000566DGR pin configurable/selectable oscillator is a high performance solution for a wide range of applications, from embedded communications to datacom and instrumentation. Its adjustable electrical characteristics, combined with its tunable frequency range and low power consumption make it an ideal solution.
