Additionally, it is suitable for other frequency-setting applications outside of the telecommunications industry. The device’s performance features make it suitable for use in low-noise communication systems as well as in data processing and instrument control systems.

The working principle of the 500DJBD-ACH programmable oscillator is based on an electronic variable-tuning system. The device uses an electronic circuit consisting of an oscillator, high-speed capacitor array, and low-speed switch members. The oscillator produces a fixed-frequency signal whose frequency is adjusted by the capacitor array in response to external control signals. The high-speed capacitor array is tuned in response to the external control signals, and the change in capacitance modifies the frequency of the output signal. The low-speed switch members allow the capacitor array to be tuned simultaneously or independently in response to different control signals or to specific operating conditions.

The system performance of the 500DJBD-ACH programmable oscillator is quite impressive. The capacitance range of the device is 7-200 pF, and it can provide an output frequency of up to 200MHz. Source phase noise is controlled to a maximum of – 72 dBc/Hz over the 0.1–30MHz range, and –110 dBc/Hz over the 30–150MHz range. The device is designed to operate in the temperature range of – 40°C to 85°C, and the frequency stability of the device is maintained to ±25ppm over the temperature range. The device is also designed to survive power-on/off over-voltage conditions.

In conclusion, the 500DJBD-ACH programmable oscillator is a highly reliable and efficient device that is suitable for a variety of communication and data processing applications. The device features an electronic variable-tuning system and a wide operating temperature range. Additionally, it provides excellent system performance with a maximum phase noise of 110dBc/Hz and a frequency stability of ±25ppm. This makes the 500DJBD-ACH an excellent choice for use in applications where a high degree of accuracy and stability is required.
