The CY7B9910-7SXC is composed of three components, an oscillator component, a clock reference component and a controller component. The oscillator component generates the input frequency and the clock reference component converts the input frequency into a compatible clock signal. The controller component configures the device parameters, like frequency range, frequency selection, VCO variation, and modes of operation. It can also provide a data rate selection and a power saving mode.

The oscillator component consists of two independent quartz-crystal oscillators which can generate frequencies up to 125MHz. The quartz-crystal oscillators have a wide range of adjustment parameters including gain and tunability. This provides the designer with the flexibility to control the center frequency, as well as the frequency range. The oscillator component also features an automatic trimming algorithm which ensures the oscillator output remains within the desired parameters.

The clock reference component consists of two voltage-controlled oscillators (VCOs). The VCOs are used to convert the input frequency into a compatible frequency. The VCOs feature a wide range of adjustment parameters, such as gain and tunability. This allows the designer to select the desired frequency range, as well as the desired frequency separation for precise timing and synchronization.

The controller component allows the user to configure the device. The controller includes a range of features, such as frequency selection, circuitry control, phase control, data rate selection and power saving mode. The device offers the capability to select multiple output channels and have them synchronized together. It can also support multiple output modes, such as single-ended, differential, pseudo-differential, halt-mode and burst-mode output.

The device features many advantages such as low power consumption, low cost, excellent jitter performance, improved phase noise reduction and reliable oscillator performance. This makes it suitable for a wide range of applications such as communication systems, clock recovery, frequency synthesis, reference clocks, and timing systems.

In summary, the CY7B9910-7SXC is a high-performance clock generator optimized for low-jitter, low cost operation.
