As technologies advance, the need for accurate timing and precise clock and signal generation become even more essential for reliable and improved performance of applications. CY24901ZXC is an ultra-low jitter clock generator, PLL and frequency synthesizer product for next-generation high-performance, low-power logic applications. It provides a safe, consistent and predictable clock performance for various applications where improved signal integrity is required. Here we will discuss the application fields and working principle of CY24901ZXC.

CY24901ZXC is a highly flexible and low-jitter clock generator which provides 1, 2 and 3-step clock generation with a wide supply range from 0.7V to 1.8V and up to a 200MHz output frequency. It supports a variety of input source types, including USB/LPC, I2C, SPI, UART and PCIe. Its integrated PLL provides functions such as frequency matching, jitter attenuation, and clock multiplications. The CY24901ZXC Dual-output DLL (Delay-Locked Loop) provides options such as output delay control and I/O Edge Control. The device is available in a tiny 1.2mm x 1.2mm 24-bump WLCSP (Wafer Level Chip Scale Package).

CY24901ZXC is designed to offer an improved signal integrity. It supports up to ±100ppm frequency adjustment, 100fs of jitter, 48mA of output drive, and excellent EMI performance. CY24901ZXC is ideal for single and dual-rail applications such as data processing, memory interfacing, system control, optical communications, low-power peripherals, and RF communications. It is also suitable for applications that require low-EMI inputs and ultra-low jitter such as ARM-based systems and high-speed peripheral applications.

The CY24901ZXC uses a fully synchronous architecture for its clock and frequency synthesizer. The device consists of an oscillator block with selectable output drivers, a phase-locked loop (PLL) block with integrated frequency synthesizers, a skew random access memory (SRAM) interface block, a third-order Delta Sigma modulator (DSM) and a master clock generator. The clock and PLL blocks are powered by the oscillator, while the SRAM block is powered by the PLL.

The oscillator block is the heart of the CY24901ZXC and is responsible for free-running oscillations. The oscilator is connected to the PLL block through a phase shifter and gain block. The phase shifter is used to ensure that the oscillation stays centered and the gain block is used to ensure the supply of a constant power to the PLL. The PLL block is responsible for lock management and also handles frequency synthesizers and output drivers. The SRAM block handles SRAM interface operations, such as flat start-up timing and safe operating points. The DSM block performs the time-to-digital conversion, which is used for noise management. The master clock generator block generates the control clock and provides timing reference for the other blocks.

The CY24901ZXC uses a combination of internal and external components to ensure accurate timing. The internal components provide the main timing elements and the external components provide the power and control signals. The internal components include the oscillator, phase shifter, PLL, DSM and master clock generator, while the external components include the transistors, resistors and capacitors. The external components provide the necessary electrical features and control functions for the clock generator.

The CY24901ZXC utilizes an advanced process technology to achieve ultra low-jitter and accurate clock performance. The device is built using an advanced process technology for improved signal integrity performance and advanced power management for improved power efficiency. CY24901ZXC also has integrated differential signal control logic to reduce the complexity of system design.
