The CY29653AXI is a programmable clock generator and buffer designed specifically to meet the needs of high-speed data systems with ever-evolving frequency requirements. The device provides support for eight different clock outputs and multiple operating modes, making it well suited for a wide range of applications. Its programmable design enables engineers to easily integrate the device into existing systems and easily adjust the clock settings on demand.

The CY29653AXI consists of a buffered low-power integrated clock generator and multiple outputs capable of providing up to eight system clock frequencies at Clock/Timing frequencies up to 200MHz in single-ended LVCMOS and LVDS outputs. It works with a variety of system speeds, making it suitable for a wide range of applications, such as communications, cable modems, digital subscriber lines, optical networks, as well as general purpose clock needs.

The CY29653AXI supports both jitter cleanup and clock multiplication. Its integrated clock multiplication circuitry allows output frequencies to be adjusted to suit the needs of the system. It also provides jitter attenuation for reduced system noise and zero-skew outputs for improved clock synchronization. By properly matching the device configuration to the optimal operating frequencies and entering the desired settings into the on-chip registers, the CY29653AXI can be used to produce a wide range of different output frequencies with minimal jitter, making it ideal for edge-of-network timing systems and other demanding applications.

The device also provides various operating modes, including phase-locked loop (PLL) phase-locked loop (PLL) phase-locked loop (PLL) phase-locked loop (PLL) phase-locked loop (PLL) phase-locked loop (PLL) phase-locked loop (PLL) phase-locked loop (PLL) phase-locked loop (PLL) phase-locked loop (PLL) phase-locked loop (PLL) phase-locked loop (PLL) phase-locked loop (PLL) phase-locked loop (PLL) phase-locked loop (PLL) phase-locked loop (PLL) frequency, spread spectrum modulation, and independent source synchronous mode. In PLL operating mode, an internal multiplier with an adjustable multiplier ratio allows the device to product users’ desired output clock frequencies. In spread spectrum mode, the device is able to reduce the system power consumption and reduce the radiated electromagnetic interference at the output clock frequencies. Last but not the least, in synchronous mode, the device can act as an independent source clock, generating output clocks with the same frequency and phase as the input clock.

CY29653AXI has also integrated several features to ensure proper operation. The device has been tested to withstand a wide range of conditions from -40°C to +85°C that are often found in consumer electronic, automotive and computer applications. It supports external system reset input, voltage supervisor function and multiple clock trimming options. In addition, the CY29653AXI provides an enhanced testing ability via the programming interface that allows each individual output to be individually tested and adjusted.

The CY29653AXI is a versatile, programmable, and cost effective solution to meet the most demanding clock distribution requirements in high speed, heavy data systems. With its range of operating modes, integrated clock multiplication and jitter attenuation capabilities, and easy integration into existing systems, it is an ideal solution for various application fields, such as communications, cable modems, digital subscriber lines, optical networks, and general purpose clock needs.
