Programmable Oscillators

Oscillators are circuits that produce periodic waveforms, literally oscillating between two levels without any amplitude growth or decay. From simple time-keeping circuits to clocks for CPUs and modems, oscillators are integral to electronic systems. Of all the types, programmable oscillators are relatively new inductees to system circuitries, offering design engineers greater control over the output frequency and other characteristics.

The SG-8003CE-PEB is an example of a programmable oscillator. It is temperature-controlled voltage-controlled crystal oscillator (TCVCXO) that provides access to a wider range of frequencies than standard crystal oscillators. With a minimum frequency of 10 kHz, a maximum frequency of 800 MHz, low Phase Noise of -140 dBc/Hz at 10 kHz offset and 0.25ppm of frequency stability over a -40°C to +85°C temperature range, the SG-8003CE-PEB is suitable for precision timing needs in SoC, base stations, wireless infrastructure, IoT and many other applications.

In addition to superior frequency control, the SG-8003CE-PEB is highly programmable. A crystal reference coupled with passive components for frequency-control elements can be programmed using a proprietary software interface. The programmable nature of the SG-8003CE-PEB makes it an ideal solution for applications that require multiple frequency setting options. It supports both frequency up-conversion and frequency down-conversion, the latter of which is used to reduce power loss and increase power efficiency.

The SG-8003CE-PEB works on a two-stage phase-locked loop (PLL) architecture. Its onboard VCO is phase-locked to the reference oscillator with adjustable frequency synthesis. The amplitude of the VCO\'s output waveform is then regulated using the voltage control line. The VCO\'s output is digitized and the phase errors are then corrected so that the PLL can be locked. Frequency tuning is done using the I2C control interface, which allows the speed and accuracy of frequency settings to be adjusted. This is then used to provide a precise and accurate output frequency.

The SG-8003CE-PEB is designed to provide high reliability with a reduced component count. Its compact form factor allows for ease of integration with existing circuit designs. The pin-out is optimized so that the connections are straighforward and flexible; this ensures that the component is easy to implement in to new and existing circuit designs. The low power consumption of the device ensures that power draw is minimized, and its low-cost manufacturing process makes the component highly cost-effective.

The SG-8003CE-PEB is an example of a programmable oscillator that provides designers with a range of options for precise timekeeping and frequency setting. The component is suitable for applications that require precise timing and frequency synthesis, including digital signal processors, wired-wireless communication systems and industrial automation.
