Programmable Oscillators are oscillators intended to be general-purpose solutions for a variety of applications with programmable differences that allow the user to customize the device to suit any given application. Additionally, they can have adjustable settings to enable the user to quickly tune or optimize the frequency or timing parameters to best suit the application. One such programmable oscillator is the SG-9101CA-C20PHBAC.

The SG-9101CA-C20PHBAC is a versatile, configurable programmable oscillator, capable of producing frequencies from a few kHz to hundreds of MHz. It is optimized for applications such as telecommunications, instrumentation, consumer electronics, networking and consumer audio/video equipment. Typical applications include oscillators for digital signal processing, frequency synthesizer designs, microcontroller clock sources, clock generators, and communication interface devices.

It features a low power consumption of 1.2 mW at 20 MHz, a wide output frequency range from 1kHz to 200 MHz, a low jitter of 50 ps (RMS) max, fast programming times and a wide temperature range of -40°C to +85°C. The SG-9101CA-C20PHBAC also has programmable input voltage and is adjustable with a 10:1 frequency range on the output from the internal PLL. Additionally, the SG-9101CA-C20PHBAC can be synchronized with a variety of external clock sources and is available in a variety of packages.

The main components of the SG-9101CA-C20PHBAC are the PLL circuit, voltage controlled crystal oscillator (VCXO), crystal filter, output buffer, and PLL control logic. The PLL circuit consists of a phase detector, low-pass filter, and voltage controlled oscillator (VCO). The phase detector can compare signals from the reference signal to the internal VCO, and it can adjust the VCO frequency so that the phase of the internal VCO signal can be aligned with the reference signal.

The VCXO generates a signal with a frequency determined by the crystal value and the external voltage control. The signal from the VCXO is then applied to the crystal filter. The crystal filter acts like a band-pass filter, allowing only the frequency that matches the resonant frequency of the crystal filter to pass. The output of the crystal filter is connected to the output buffer, which amplifies the signal and converts it to the required output signal format.

Finally, the SG-9101CA-C20PHBAC can be programmed through a serial port using a variety of commands. It uses a serial communication port to set or change its frequency or other internal parameters. It can also be programmed with a Crystal Frequency Parameter (CPP) or multiple crystal frequencies. To program the SG-9101CA-C20PHBAC, a system containing the required hardware and software must be used, or an external programmer.

In conclusion, the SG-9101CA-C20PHBAC is a versatile programmable oscillator, which provides a wide range of frequencies and can be used in a variety of applications. It is particularly suitable for applications such as telecommunications, instrumentation, consumer electronics, networking and consumer audio/video equipment. Additionally, it is low power consuming and features fast programming times and a wide temperature range.
