The pin selectable Oscillator DSC400-4444Q0059KE2T includes an integrated regulator, a low-noise clock signal generator and a switchable PLL circuit which makes it a highly reliable and cost-effective solution for applications that require an adjustable frequency. The triangular wave output of the oscillator is used as the reference frequency for the PLL circuit. The clock is then adjusted according to the frequency required by the user application.

The circuit contains 3 internal voltage reference, 2 external references and 4 digital control pins. These pins are used to set the output frequency, operating frequency, PLL parameters and operating temperature. By changing the values of the digital control pins, the output frequency and the operating frequency can be individually adjusted.

The onboard phase-locked loop (PLL) circuit is responsible for stabilizing the frequency output of the oscillator over a wide range of operating conditions. It enables users to set the output frequency of the oscillator dynamically and precisely with a minimal frequency error. It also simplifies the tuning process by eliminating the need for additional calibration for PLL operations.

The DSC400-4444Q0059KE2T oscillator uses a combination of computational intelligence and advanced power management techniques to reduce the quiescent current when the device is not running and extend the battery life of the user application. The chip also includes a low-power sleep mode which further reduces the current consumption when the user application is not active.

The DSC400-4444Q0059KE2T oscillator is highly configurable and features a programming interface which allows the user to select specific oscillator parameters such as frequency, power supply, operating temperature, and output amplitude. The programming interface also supports both parallel and serial programming.

The device is designed to provide superior noise performance with low jitter, low phase noise, and high SMSR performance. It also supports a wide frequency range from 100 kHz to 300 MHz. The operating temperature range of the DSC400-4444Q0059KE2T oscillator is from -40°C to 85°C.

In summary, the DSC400-4444Q0059KE2T is a highly configurable and programmable oscillator which offers a cost-effective and reliable solution for various applications in the telecommunications, industrial, and embedded systems markets. It is suitable for use in applications that require low-noise, high-switchable, and adjustable output frequency, phase noise, and jitter.
