BU7814KN-E2 is an audio special purpose product developed by Toshiba Semiconductor Co., Ltd. It is an audio experience to listen to and evoke powerful effect.
Application Field
BU7814KN-E2 is applied as a sound system. It has strong sound, good power processing capability, low power consumption and miniaturized package. It is widely used as a sound system for antenna systems and audio amplifiers, for mobile communication base stations or communication sector isolation systems.
Working Principle
BU7814KN-E2 consists of a main oscillator and a buffer amplifier. The main oscillator is modeled by a phase-locked loop (PLL) filter that optimally compensates the phase, frequency and amplitude offsets. The phase-locked loop is used to generate the output signal frequency according to the predetermined oscillation frequency, and the buffer amplifier is used to amplify the signal output from the main oscillator. In addition, the output signal can be adjusted in frequency and amplitude, so that signals with different characteristics can be obtained.
The main oscillator consists of a voltage-controlled oscillator (VCO), phase-frequency detector (PFD), charge pump (CP) and loop filter (LPF). The oscillation frequency is determined by the voltage-controlled oscillator, and the other parts, including phase-frequency detector, charge pump, and loop filter, compare the output of the voltage-controlled oscillator with the reference frequency. Error signals generated by the comparison will be tuned and amplified by the charge pump, and the loop filter will be adjusted until the output of the voltage-controlled oscillator is equal to the reference frequency.
The BU7814KN-E2 then includes a buffer amplifier, consisting of an inverter, a low-pass filter, and a high-pass filter. The inverter amplifies the signal from the main oscillator, and the low-pass filter and the high-pass filter are used to eliminate any high-frequency interference. The buffer amplifier provides power for the signal at the output stage and further improves the signal-to-noise ratio.
In summary, BU7814KN-E2 is a special purpose audio device used for audio systems. It adopts a highly reliable PLL filter and amplifiers to achieve more clean and powerful sound effects, and its purpose is to give the user the best experience possible in terms of sound innovation.
