CY7B992-7JI is a clock and timing components designed by Cypress Semiconductor. It is an ideal solution for clock and timing applications, and belongs to the Clock/Timing category: Clock Generators, PLLs, Frequency Synthesizers.

CY7B992-7JI is built-in a PLL circuit that provides a high frequency clock signal and a BiCMOS logic function. It has a two-stage frequency synthesizer with user-programmable dividers, enabling it to output any frequency from 400kHz to 325MHz in a frequency-locked mode. The device also features on-chip, user-programmable phase shifts for all output types. With a small 8-pin flat-pack package, it is ideal for small designs.

This clock and timing component also has programmable slew rate control and output power, resulting in clean clock waveforms. It offers a range of on-board features, such as power down and tri-state, making it very flexible in a range of applications. The CY7B992-7JI has built-in clock- or data-driven phase-lock loops, allowing the user to program multiple bit cells with phase delay or frequency swapping. It also includes an IEEE 1149.1-compliant boundary scan boundary-scan interface, enabling boundary-scan testing in high-speed digital designs.

Applications of CY7B992-7JI include digital signal processing and communications, such as cellular base stations, routers, and switches. It is also ideal for digital multimedia, audio, and professional audio/video applications; and for image processing, RF-ID (radio frequency identification) systems, test and instrumentation, and other application areas.

CY7B992-7JI’s working principle lies in the frequency synthesizer circuit, which is a combination of several dividers and phase detector blocks. The frequency divider block has a set of dividers that divide the reference frequency of the clock source. This led to the outputof different frequency. The Phase detector block will detect the phase difference between the input signal and output signal and can control the voltage control oscillator (VCO) to output the desired frequency.

The CY7B992-7JI combines the two blocks above in a single integrated product, thus saving customers a considerable amount of space. It also boasts of a low-phase noise and low power consumption which make it the ideal choice for high-end clock and timing applications.

CY7B992-7JI is an efficient and reliable clock and timing components. It offers users many features in a small, 8-pin package. The PLL circuit presents a wide range of frequency synthesis and low power consumption, as well as programmable phase shift capabilities. It also has IEEE 1149.1-compliant boundary scan to easily use in boundary-scan testing in high-speed digital designs. All these features make CY7B992-7JI a complete clock timing solution for applications in various industrial, communication and consumer markets.
