Programmable oscillators are electronic devices that are used to generate an electronic signal, such as an alternating current (AC) or a direct current (DC), that is periodic in nature. The SIT9005ACL2H-18NB is a programmable oscillator designed to generate stable, low jitter signals. It is ideal for use in applications where frequency accuracy and stability are essential.

The SIT9005ACL2H-18NB is a two-stage programmable oscillator, meaning it has two separate integrated circuits. The first stage is the voltage-controlled oscillator (VCO), which is used to generate the desired frequency. The second stage is the frequency synthesizer and divider (FSD), which is used to set the frequency of the oscillator. The frequency can be set by programming the FSD with an external clock, or by manually adjusting the frequency.

The SIT9005ACL2H-18NB is capable of generating frequencies from 0.5 Hz to 190 MHz, with a stability accuracy of +/-0.5 ppm over the entire range. The device also has a low noise level of -105 dBc/Hz and fast output rise and fall times of 6 ns. In addition, it has an integrated low power amplifier with a gain of +10.5 dB.

The SIT9005ACL2H-18NB is also designed to operate in both single-ended and differential configurations. In the single-ended configuration, the output is a sinusoidal waveform with an amplitude of 0.5 Vpp hold on to the logic-level output of the FSD. In the differential configuration, the output is a balanced sine waveform with an amplitude of 1 Vpp, providing better phase noise performance.

The SIT9005ACL2H-18NB is well suited for use in a wide variety of application fields, including clock distribution systems, frequency synthesisers, clock buffers, phase-locked loops (PLLs), pulse width modulation (PWM) systems, and more. It is also ideal for use in automotive, communication, network and consumer electronic applications. In addition, the device is RoHS compliant, making it an attractive choice for those requiring environmentally friendly components.

The operating principle of the SIT9005ACL2H-18NB is based on a concept known as phase-locked loop (PLL). A PLL is a feedback circuit that is used to synchronise the frequency of an oscillator to an external reference signal. The working principle of a PLL is to compare the internal output frequency of the oscillator with the external reference signal. Any divergence in frequency between the two signals is then corrected using a series of different control signals, allowing the internal output frequency of the oscillator to be “locked” onto the frequency of the external reference signal.

In the case of the SIT9005ACL2H-18NB, the device’s integrated VCO is used to generate the frequency of the internal output signal. This signal is then compared to the external reference signal in the frequency synthesizer and divider. Any difference in frequency between the two signals is then adjusted using a control voltage from the FSD, providing an output signal with a frequency that is “locked”on to the external reference signal.

In summary, the SIT9005ACL2H-18NB is a versatile programmable oscillator that is well suited for a variety of applications where high frequency accuracy and stability is essential. It can generate frequencies from 0.5 Hz to 190 MHz and has a stability accuracy of +/- 0.5 ppm. It is RoHS compliant and can operate in either single-ended or differential configurations, depending on the application. The device’s functioning is based on the PLL principle, which is used to compare the internal output frequency of the oscillator to the external reference signal and make the necessary corrections to ensure that the output frequency is “locked”onto the reference signal.
