CY25819SXCT is a low-jitter, high-performance clock and data recovery (CDR) device. The integrated device features a clock generator, phase-locked loops (PLLs), frequency synthesizer, and digital-to-analog converter (DAC). It is designed to provide precision clock generation and clock recovery in digital applications.

CY25819SXCT is ideal for use in high-speed serial data interfaces, digital system clocks, and sensing and measurement systems. The device offers greater than 40-dB noise isolation and is designed to operate up to 12.5 Gbps. It integrates a low-jitter clock generator, a high-speed PLL, and a frequency synthesizer. The integrated clock generator can generate up to 16 different outputs with a variety of frequency and duty cycle options.

The integrated PLL can lock to a wide range of external clock rates from 25 MHz to 3.2 GHz. It can track the incoming frequencies and adjust the internal PLL clock to match the external clock. This allows for reduced system latency and improved clock stability. It also helps ensure reliable data transmission by locking onto the incoming clock rate.

The integrated frequency synthesizer is a frequency multiplier and includes a digital-to-analog converter (DAC). It can accept input frequencies from 10 kHz to 3.2 GHz and produce output frequencies up to 6.2 GHz. The DAC enables programming of the output frequency in 256 discrete steps.

The CY25819SXCT also features a phase-detection circuit that monitors the phase error between the external clock and the output clock. The circuit monitors the phase error and adjusts the output clock frequency and phase to reduce jitter. This feature helps ensure low noise, high quality clock and data recovery.

Overall, the CY25819SXCT is a high-performance, low-jitter clock and data recovery device. It integrates a clock generator, PLLs, frequency synthesizer, and DAC to provide precision clock generation and recovery in digital applications. The device can lock to a wide range of external clock rates, provide reliable data transmission, and reduce system latency and noise.
