LC72131KMA-AE

The LC72131KMA-AE is a clock generator or frequency synthesizer used to produce very precise timing signals with the potential to be used in a wide variety of applications. This particular chip can work with either undivided or divided signals while maintaining the most accurate frequency available on the market. Before discussing the applications and working principles of the LC72131KMA-AE, it is important to familiarize ourselves with the specifications and features of the device.

The LC72131KMA-AE is a frequency synthesizer containing an on-chip voltage-controlled oscillator (VCO) with CMOS-constructs and surface-mount technology (SMT). It has a maximum frequency output of 800 MHz. Additionally, it has a low-noise buffer output that is equivalent to a standard 14-pin CDIP package and is suitable for all kinds of high-speed circuit applications. The device also has a voltage gain control range of up to ± 6.0dB and a frequency deviation range of up to ±12.5MHz. Furthermore, it has a stable output frequency and wide VCO-frequency range of up to ± 6.5 MHz.

The key applications of the LC72131KMA-AE are in high-speed digital systems, such as cellular and cordless phones, digital audio systems, computer systems, and digital video broadcasting. It can also be used in frequency division and low-noise synthesizers and modulators. Moreover, it is also used as a reference timing signal generator in radio and satellite broadcasting.

The LC72131KMA-AE works by using a voltage-controlled oscillator and a low-noise buffer output. The VCO is the main component of the chip and it uses a voltage-controlled inverter chain to convert a fixed frequency signal into a much lower frequency signal. The low-noise buffer output then amplifies and stabilizes the frequency output from the VCO so it can be used in high-speed circuit applications. Furthermore, the frequency output from the LC72131KMA-AE can be controlled by applying an external voltage signal to its voltage gain control pin.

In summary, the LC72131KMA-AE is a clock generator or frequency synthesizer mainly used in digital systems, radio and satellite broadcasting, and frequency division and low-noise synthesizers and modulators. It is able to generate a maximum frequency output of 800 MHz and it has a wide VCO-frequency range up to ± 6.5 MHz. The device is equipped with a voltage-controlled oscillator, a low-noise buffer output, and a voltage gain control. It also has an input voltage range of -24V to +24V and a frequency deviation range of up to ±12.5MHz. The chip is suitable for all kinds of high-speed circuit applications.
