The DS C6122CI2A-00B2T Bel Fuse, Inc. is a member of the Pin Configurable/Selectable Oscillators family. It is a 12-pin ceramic oscillator capable of running at frequencies up to 8.000 MHz. The oscillator’s pin options allow for two output modes or two outputs, one sourcing and one sinking, with an accuracy of ±50 PPM at 85°C.

The pin-configurable oscillator (PCO) has an internal startup resistor and a variable internal load impedance that make it ideal for a variety of applications with various power supply requirements. This device is best suited for high-speed data applications, such as clock and data conversion, as well as serial data communications. It also supports high-speed clock generation when its output pins are configured correctly.

The DS C6122CI2A-00B2T provides both single-ended and differential outputs with a maximum output swing of 500 mV peak-to-peak and a drive capability up to 15 mA. The oscillator offers a wide range of operating voltage options with different power consumption levels depending on the user’s needs. It is also equipped with a proprietary Trip-LLC protection circuit to protect the device from damage caused by sudden voltage dropouts or spikes.

The effect of power supply noise on the reliability of the oscillator is minimized through the application of innovative Wide Spread Frequency Correction (WSFC) circuitry. This circuitry maintains the frequency accuracy of the oscillator over a wide range of supply voltage and temperature variations, providing a high performance solution for clock applications where reliability and jitter control are critical considerations.

In terms of its working principle, the DS C6122CI2A-00B2T employs a phase-locked loop (PLL) with a quartz crystal as a frequency reference source. The PLL continuously adjusts the frequency of the internal oscillator in order to ensure stable oscillation frequency accuracy even during power supply noise. The oscillation frequency is set by programming one of the pins on the oscillator package which provides access to a subset of the total frequency range.

The DS C6122CI2A-00B2T is available in an extremely compact 12-pin ceramic package with low power consumption. This small form factor is well suited for applications that require a high-speed crystal oscillator in small spaces. This device is also a great choice for applications with limited levels of power consumption, such as for battery powered products.

The DS C6122CI2A-00B2T oscillator provides high performance and low cost in a total solution for many clock and data applications. This highly reliable device offers optimal frequency control through its built-in startup resistor network and its proprietary Wide Spread Frequency Correction (WSFC) circuit. It is a great choice for applications that require reliable, stable frequency accuracy in noisy power supply environments.
