Programmable oscillators are a type of timing component designed to provide an output signal of a fixed frequency and/or amplitude. They are a controllable and versatile type of oscillator suitable for use in a wide range of applications. SG-9101CE-C05PGBAA is a programmable oscillator manufactured by Silicon Labs that has been designed to be highly reliable, cost effective, and easy to use. In this article, we will look at the application field and working principle of the SG-9101CE-C05PGBAA.

Application Field

The SG-9101CE-C05PGBAA is specifically designed for use in crystal oscillator designs. It is an ultra-low phase noise and temperature stable programmable crystal oscillator (TCXO). It offers superior phase noise performance at frequencies from 10 kHz to 10 MHz. The device is ideal for use in clock recovery, phase-locked loop (PLL) and synchronization designs for wireless transmission and digital communication systems.

The SG-9101CE-C05PGBAA is also suitable for use in I2C, SPI, and single wire applications and can be easily programmed using the TruelyTouch graphical programming user interface. This makes the device suitable for a variety of different applications, such as clock generation, frequency-hopping spread spectrum, base stations, and defense applications.

The device is also RoHS compliant and offers up to -85 dBc/Hz phase noise in the 10 kHz to 500 kHz range, low VCO jitter of 0.2 ps, and a wide tuning range of 1 to 10 MHz.

Working Principle

The SG-9101CE-C05PGBAA works by using an embedded ECL (Emitter-Coupled Logic) oscillator circuit. The device can be programmed to output a wide range of frequencies, from lows of around 10 kHz up to high frequencies in the 10 MHz range. The output frequency can be adjusted in 1 Hz steps or 100 Hz steps depending on the desired accuracy.

The device uses an external crystal as the reference frequency source. It utilizes a combination of divider chains and logic gates to produce the output. The crystal oscillator is connected to the device’s input and the oscillation frequency of the crystal determines the output frequency of the oscillator.

The device can be programmed using the TruelyTouch graphical user interface. This allows the user to easily adjust the output frequency, phase noise, and other parameters as required. The device can also be controlled over I2C, SPI, and single wire interfaces.

Conclusion

The SG-9101CE-C05PGBAA is a highly reliable and cost effective programmable oscillator from Silicon Labs. It is designed for use in crystal oscillator designs, and is suitable for a wide range of applications such as clock recovery, phase-locked loop, synchronization, and I2C, SPI, and single wire applications. The device can be easily programmed using TruelyTouch graphical programming user interface to ensure accurate tuning. The device also has superior phase noise performance, low VCO jitter and a wide tuning range of 1 to 10 MHz.
