CY28517ZXCT Application Field and Working Principle

CY28517ZXCT is a low power programmable delay line with a single access port and clock synchronization system by Cypress. With its industry standard footprint, it is designed for applications such as clock and timing synchronization. As a clock synchronization system and a programmable delay line, it has a wide range of applications in clock generation, clock multiplying, clock spreading and frequency offset adjustment.

CY28517ZXCT has an 8-bit single port programmable delay line with 32 clock outputs. The slew rate of the clock output can be automatically adjusted to match the clock rate and/or other outputs according to the user\'s settings. It also has NVSRAM (Non-Volatile Static Random Access Memory) for storing on-chip trim values such as Vlow, Vhigh, VlowRS and VhighRS. All of the configurations can be easily controlled by external logic, allowing the user to select their desired clock rate, delay and spread.

CY28517ZXCT is based on a low-power CMOS process, and its synchronization system can achieve very low power consumption without sacrificing any performance. It supports 3.3V and five differential output options. It provides customers with very high flexibility in terms of performance and power consumption.

In terms of working principle, CY28517ZXCT uses a crystal oscillator or clock generator to generate the clock signals. Then, before the signals are sent to the outputs, they are divided and passed through multiple synchronizers, thus achieving synchronization. The length of the delay line varies depending on the specific application. The user can also adjust the slew rate of the clock output to suit their needs.

Finally, the synchronizers output the clock signals to the outputs. This output can be used for clock generation, clock multiplying, clock spreading and frequency offset adjustment. These output signals can be used for generating a local clock, for synchronizing different systems, or for creating a jitter-free data stream.

CY28517ZXCT is an excellent choice for applications requiring low-power, synchronization of clock timing, and programmable clocks. Its small form factor and ability to use both single-ended and differential outputs make it ideal for many applications. It is widely used in various industries including consumer electronics, automotive and aerospace due to its low power consumption and exceptional performance.
