CY29940ACT

Clock Buffers, Drivers Overview

The CY29940ACT is a fanout buffer manufactured by Cypress Semiconductor Corp, designed for clock distribution applications. It features a 2:18 input-to-output ratio and supports a maximum frequency of 200 MHz. The device accepts LVCMOS, LVPECL, or LVTTL inputs and provides LVCMOS or LVTTL outputs. It operates within dual voltage ranges of 2.375V to 2.625V and 3.135V to 3.465V. Packaged in a 32-TQFP (7x7) surface-mount case, it functions at temperatures between 0°C and 70°C.

Clock Buffers, Drivers Procurement Notes

Verify the specific suffix 'ACT' against official Cypress documentation to confirm temperature range and package variations. Ensure compatibility with existing board layouts for the 32-TQFP footprint. Check current availability status as component lifecycles may change.

Clock Buffers, Drivers Selection Notes

Select this component when a single clock source needs to drive up to eighteen loads with minimal skew. Confirm that the system power supply aligns with the specified 2.5V or 3.3V operating ranges. Verify input signal levels match the supported LVCMOS, LVPECL, or LVTTL standards.

Clock Buffers, Drivers Part Context

This part belongs to the Cypress clock buffer family, which provides low-skew distribution solutions. The CY29940 variant specifically offers high fan-out capabilities compared to lower-ratio buffers in the same series, suitable for complex multi-load timing requirements.

Clock Buffers, Drivers Replacement Considerations

Consult official replacement guides for direct equivalents. Verify pinout compatibility and electrical parameters if substituting with similar 2:18 buffers from other manufacturers.
