SY87700LZI is an application specific clock generator IC. The device is based on a voltage-controlled oscillator (VCO) and is renowned for its high performance and stability. It is used to generate timing and clocking signals and is found in many consumer and industrial applications.

The SY87700LZI features a wide range of programmable functions, including a built-in oscillator, wide range of output frequencies, high stability, and temperature compensation capability. The device can be used in an array of applications, including audio, video, and communications.

The working principle of SY87700LZI is based on a voltage-controlled oscillator, which uses a circuit to exploit the relationship between the input DC supply and the frequency of the pulsed output signal produced. Depending on the voltage characteristics of the oscillator and its components, the output frequency of SY87700LZI is programmable. The VCO is composed of an output buffer driving a tank circuit with a delay and gain element. The frequency of oscillation is based on the capacitance of the tank and the transconductance of the voltage-controlled amplifier.

The built-in VCO consists of a frequency output buffer and a tunable tank. A variety of frequency ranges and clock outputs can be achieved by tuning the tank circuit. This allows the VCO to produce precise and stable signals with different frequencies and slope delays. As a result, the VCO can provide very precise signals in the presence of significant noise and temperature variation.

The clock output of the SY87700LZI can control the output frequency with linear and non-linear signal profiles. Some of the available functions are pulse modulation, pulse-width modulation, duty cycle modulation, and frequency modulation. It can also be used together with a programmable sequencer to generate a variety of signals with different frequencies, duty cycles, and signal profiles.

The SY87700LZI features multiple clock outputs, allowing it to provide various clock signals for various pieces of digital circuitry in the same device. The device can be used to generate synchronous clock signals for digital circuits and applications such as ADC, DAC, Digital Audio, Video Systems and more. The device also features a selectable divide-by-two low-frequency output (LFO), which can be used for frequency modulation, pulse modulation and more.

The SY87700LZI is a high-performance and ultra-reliable clock generator IC, providing time-critical applications such as audio and video in consumer, professional, industrial and automotive applications with low-noise and accurate output signals. The device combines low power consumption, high versatility and reliable operation to ensure best performance in the most demanding environments.
