Introduction

RE46C190S16F is a 16-pin low voltage CMOS fixed frequency oscillator programmed for a supply voltage range of 2.0V to 3.6V. This product has been designed to increase the cost-effectiveness of low voltage applications such as wireless data transmission, portable communications and embedded microprocessors. It operates with a supply current of 30uA, making it a very low power device. The RE46C190S16F’s specific frequency range is 3.2-35.3KHz and has a wide tolerance of +/-2%. In addition, the RE46C190S16F incorporates two separate oscillator pins (XIN and XOUT) which can be used to configure frequency division ratios, providing users with more flexibility in their applications.

Application Field

The RE46C190S16F is targeted at embedded microprocessors and communication applications where low power is required. For embedded microprocessor applications it can be used as a clock source when the original microprocessor’s oscillator is not suitable. For example, it can be used to reduce the start-up time or to increase the system performance and reliability. Other application fields include TV systems, airbag systems, transmissions and remote control systems.

Working Principle

The RE46C190S16F operates on a fixed frequency range from 3.2-35.3KHz and includes two separate oscillator pins (XIN and XOUT) which can be used to configure frequency division ratios. The RE46C190S16F is essentially an electronic oscillator that uses a capacitor and resistor to generate periodic electrical signals. The RE46C190S16F maintains a stable frequency output over a wide temperature range due to the onboard temperature compensation circuitry.When a voltage is applied across the capacitor and resistor, current flows alternately between the two. This current flow creates a voltage drop across the capacitor, which is stored as the capacitance builds up. The capacitor can only store a certain amount of charge, at which point the potential across it is zero, and the current stops flowing. As the voltage across the capacitor starts to fall, the current begins to flow in the opposite direction and the voltage starts to increase. This process continues in a cycle, creating a sine wave. The RE46C190S16F is programmed to generate this sine wave in the frequency range stated above.

Conclusion

The RE46C190S16F is a 16-pin low voltage CMOS fixed frequency oscillator programmed for a supply voltage range of 2.0V to 3.6V. It operates with a supply current of 30uA, making it a very low power device. The RE46C190S16F is specifically designed to increase the cost-effectiveness of low voltage applications such as wireless data transmission, portable communications and embedded microprocessors.
