SIT1602AC-81-33E-48.000000T

Oscillators are electronic circuits that constantly produce periodic waveforms. The SIT1602AC-81-33E-48.000000T is a type of oscillator, specifically a temperature-compensated Voltage Controlled Oscillator (TCVCXO).

Application Field: TCVCXO oscillators are commonly used for timing applications in communications and media equipment. They are used as precision clock sources for baseband processors, as frequency reference sources for wireless local loop functions, and as local clock sources for servers, routers and switches. Additionally, TCVCXOs are deployed in GPS receivers and in WBG-certified WiFi/LTE/EPC/M2M devices.

Working Principle: The SIT1602AC-81-33E-48.000000T makes use of a quartz crystal oscillator circuit to generate stable, low-skew clock signals. It consists of a temperature-controlled quartz crystal resonator, an amplifier, and an automatic gain control (AGC) circuit. The quartz crystal resonator is responsible for generating a stable, periodic signal which is then amplified by the amplifier and regulated by the AGC circuit. The voltage applied to the circuit is used to control the frequency of the output signal.

The SIT1602AC-81-33E-48.000000T also has built-in temperature compensation functionality, meaning that it can automatically change its frequency in response to changes in temperature. The compensation allows for a highly precise frequency output that is resilient to variations in the environment. This feature makes TCVCXOs suitable for extreme temperature conditions, such as in aviation and satellite applications.

The SIT1602AC-81-33E-48.000000T is available in a standard hermetic package, with typical startup times of less than 100 ms, an output impedance of 8 ohms, and a phase-noise of –115 dBc/Hz 10 kHz away from a 10 MHz center frequency.

In summary, the SIT1602AC-81-33E-48.000000T is a temperature-compensated Voltage Controlled Oscillator (TCVCXO) that is used in communications, media, and industrial applications where it is necessary to maintain precision timing over a wide range of temperatures. This oscillator is able to provide an exceptionally accurate and stable frequency output even under extreme environment conditions.
