Programmable Oscillators are widely used in a variety of situations to provide a reliable oscillation signal over a wide bandwidth with fast tuning speeds, low jitter and low noise. The SG-9101CG-C05PGDBB is an example of these and combines low-noise and low-power performance with a wide frequency tuning range for a reliable and robust solution.

At its core, the SG-9101CG-C05PGDBB is a voltage-controlled oscillator (VCO) that is integrated into a ceramic package. This particular oscillator runs on 5V and can generate an output frequency range of 9 - 100MHz. It also supports a wide voltage control range of 0.2 - 5.0V with a maximum tuning sensitivity of 25MHz/V. The output amplitude can be adjusted to as low as -10dBm and as high as +3 dBm when needed.

Furthermore, the SG-9101CG-C05PGDBB has low jitter performance of 1ps RMS and an extremely small phase noise of -135dBc/Hz@100kHz for precise timing applications. With regards to power consumption, the SG-9101CG-C05PGDBB has an extremely low power consumption of only 8mA - 15mA, making it an ideal choice for battery-powered applications.
