Oscillators are electrical and mechanical devices whose output is an AC waveform. In the context of electronics, we are typically referring to oscillators as frequency sources. They typically take the form of an LC tank circuit, a crystal, or a transistor based feedback circuit.The SIT1602BI-72-XXS-74.176000D Oscillator is a specialized oscillator specifically designed to accurately generate a 74.176kHz clock frequency. It is ideal for applications that need an ultra-low jitter clock source and provides a wide operating range of 1.8V to 3.3V with internal ESD protection.This device is most notably found in audio applications, such as CD-ROM and DVD-ROM optical discs and A/V equipment, as well as realtime communication applications like USB, PCIe, and Ethernet. It has also found use in intelligent lighting, medical equipment, and industrial applications.The SIT1602BI-72-XXS-74.176000D Oscillator uses a bipolar-based CMOS inverter circuit augmented by on-chip components to produce its outputs. It includes dedicated components such as a resistor, a capacitor, a transistor, and a voltage controlled oscillator (VCO) to create an oscillatory signal. The output of this signal is then amplified and tweaked with the help of the on-chip components for accuracy and stability.This oscillator boasts exceptional jitter performance, with a Phase Jitter (not random) of 0.9ps. It also features excellent system noise immunity, with a 0.5mV ripple-and-noise level and an ESD protection of±2000 instead of the typical ±1000V. With better protection, the risk of premature oscillator failure due to external transient events is minimized.The SIT1602BI-72-XXS-74.176000D oscillator is capable of exact frequency calibration, controlled over the ±100ppm range with two independent external frequency control pins, which enable the user to adjust the frequency of the device with extreme precision.In addition, its low power consumption ensures improved battery life for applications using this oscillator. It requires 10μA max supply current at the output enable pin (OE low). With operations tightened up and less power consumed, it can stretch the effects of applications in the current market. The SIT1602BI-72-XXS-74.176000D Oscillator has proven to be an excellent choice for applications where low jitter and low power are essential. It\'s an invaluable asset in providing accurate and reliable clock signals and has ample useful features to deliver superior performance.
