Oscillators

Oscillators are electronic devices, either in the form of integrated circuits or transistors, used to generate varying electrical signals with different frequency levels. These oscillating signals are used in many electronic applications, such as radio and audio systems, to drive the operation of many digital systems and circuits. SIT1533AI-H4-DCC-32.768E is one such oscillators used to generate repeating timing signals from 32.768 KHz crystal.

Application Field

The SIT1533AI-H4-DCC-32.768E is an ultra-low power oscillator with stability and reliability. It generates a repeating signal at a frequency of 32.768 KHz and is designed for low power applications such as those that use watch or timing crystals. It is ideal for system clocking, timing and low power portable applications requiring extended hold-up time.

The SIT1533AI-H4-DCC-32.768E can be used in medical implants, health monitoring systems, wireless sensing solutions, IoT applications, and other wearables. It is extremely reliable and consumes very low power when compared to other clock solutions.

Working principle

The SIT1533AI-H4-DCC-32.768E operates on the principle of generating a repeating signal from a crystal by exploiting the piezoelectric effect. The basic concept is that when electrical stimulus is applied to a quartz crystal, it oscillates at its natural resonant frequency, known as the fundamental resonance. The SIT1533AI-H4-DCC-32.768E uses this principle to generate an output signal from the 32.768 KHz crystal that is then used to drive designs and system clocks.

The operation of this device consists of two parts. The first part is a voltage-controlled oscillator (VCO) which can be used to adjust the frequency of the clock signal. The VCO can be tuned in steps by applying a voltage to the VCO input. The second part of the device is a programmable divider that can be used to divide the signal by a number specified by the user.

The SIT1533AI-H4-DCC-32.768E also includes dedicated power signaling pins and current sensing circuitry. This helps conserve power by shutting off the device when it is not in use, or when the battery voltage is low. The device also features a separate reset output pin to ensure synchronized power cycling.

The SIT1533AI-H4-DCC-32.768E is an incredibly versatile oscillator that can help reduce power consumption and improve overall system performance. It is a reliable and affordable choice for low powered applications needing accurate timing.
