Application Field

The CY29947AXCT is a clock buffer perfect for high-speed applications such as data communications, video and audio applications, and high-speed synchronous logic applications. It is commonly used in system boards, telecom and LAN applications, video boards, telecom power supplies, and system-level timing solutions.

Working Principle

The CY29947AXCT is a 3-tap pseudo-triangular drive buffers that operates with a 500MHz bandwidth and able to generate 8 TTL/LVCMOS outputs. It is designed to match the output of oscillators, PLLs and other clock source up to 500MHz while minimizing the output-to-output skews. It features differential outputs and input buffers with pre-emphasis, duty cycle correction and FET-based output stages.

The power supply for the CY29947AXCT supports a wide voltage range from 2.5V to 3.3V and is optimized for low power consumption. It supports a temperature range of -40°C to 85°C with no derating.

The CY29947AXCT also features a programmable slew rate control and much lower clock output jitter compared to standard clock drivers. The clock output jitter remains very low and is tightly controlled across the full operating temperature range. The CY29947AXCT is designed with optimized signal integrity to ensure superior performance, even with long wiring traces.

In addition, the CY29947AXCT features on-chip terminate and power sequencing of the outputs to ensure proper power-on sequencing the board level. This makes it easy to use, and the simple board layout will reduce signal reflections, crosstalk and other noise.

Conclusion

The CY29947AXCT is an ideal solution for high-speed applications requiring low skew and jitter. It is cost-effective, small, and can be easily integrated into any design. With the low power consumption and wide temperature range, the CY29947AXCT is a reliable and powerful choice for high-performance applications.
