CY29774AXIT

Clock Generators, PLLs, Frequency Synthesizers Overview

The CY29774AXIT is a Spread Aware PLL-based clock driver manufactured by Cypress Semiconductor. It functions as a fanout distribution, multiplexer, and zero-delay buffer with one circuit. The device accepts LVCMOS input and provides LVCMOS output in a 52-TQFP (10x10) surface-mount package. It operates on a supply voltage of 2.375V to 3.465V and supports a maximum frequency of 125MHz. The component includes an integrated divider and multiplier, features a 2:14 input-to-output ratio, and lacks differential I/O capabilities. It is rated for industrial temperatures ranging from -40°C to 85°C.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the manufacturer designation carefully, as listings may attribute this part to Rochester Electronics or indicate obsolete status. Confirm the specific suffix 'AXIT' matches the required 52-TQFP package and temperature range. Cross-reference datasheets to ensure compatibility with LVCMOS signal levels and 2.375V to 3.465V power requirements before integration.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when a combined zero-delay buffer and fanout driver is required for LVCMOS clocks up to 125MHz. Ensure the design accommodates the 52-TQFP footprint and 2.375V to 3.465V supply rails. Verify that the 2:14 ratio meets the system's clock tree needs and that spread spectrum support aligns with EMI constraints.
