CY27027ZXC

The CY27027ZXC is an integrated clock generator which utilizes an advanced phase-locked loop (PLL) technology to generate frequency synthesizers. It is used to generate any frequency up to 50MHz with high accuracy, low jitter and low phase noise performance. The PLL circuit contains a phase detector, low pass filter, voltage controlled oscillator (VCO), and a divider. By setting the parameters of the divider and the VCO, the frequency of the output signals can be precisely calculated by the phase detector and the low pass filter.

The CY27027ZXC is mainly used in the areas of communication, digital signal processor (DSP) and digital video system. In the communication field, it is used in systems such as GSM, ADSL, WCDMA etc. for line, timing, and frequency synthesis. In DSP applications, it can be used for clock generators, memory clocking, and media processors. In digital video applications, it is used for broadcast, encoding/decoding and surveillance.

The CY27027ZXC is designed to be a highly flexible product, with many features such as programmable clock and data output formats, power saving mode, programmable spread-spectrum, a full range of programmable frequencies up to 50MHz, adjustable VCO ranges, and on-chip buffered outputs. It also has a programmable power supply range, and can generate various pulse rates.

The CY27027ZXC works by using a reference clock input to generate an output clock. The reference clock is first divided down to a lower frequency, which is then used to control a voltage controlled oscillator (VCO). The VCO is part of an LC tank circuit, which provides the most optimal frequency response and stability. The output from the VCO is then divided further down to the desired frequency, which is then buffered and output as the desired clock signal. The output clock frequency is controlled by adjusting the VCO frequency, and can be adjusted to within 0.1% accuracy.

The CY27027ZXC is a very useful and reliable device for providing clock and frequency synthesis in a variety of applications. It has the capability to generate any frequency up to 50MHz with high accuracy, low jitter and low phase noise performance. Its programmable features, adjustable VCO, power saving mode, and programmable spread-spectrum makes it suitable for a wide range of applications, from communications to digital video.
