CY29940AXI

Clock Buffers, Drivers Overview

The CY29940AXI is a clock buffer and driver manufactured by Cypress Semiconductor Corp. It functions as a fanout buffer, distribution circuit, and multiplexer within a single circuit configuration. The device supports an input-to-output ratio of 1:18 and operates at a maximum frequency of 200 MHz. It accepts LVCMOS, LVPECL, or LVTTL inputs and provides LVCMOS or LVTTL outputs. Power supply voltage ranges from 2.375V to 3.465V. The component is housed in a 32-TQFP package with dimensions of 7x7 mm and is rated for an operating temperature range of -40°C to +85°C.

Clock Buffers, Drivers Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to confirm package type and temperature grade. Confirm current availability status as product lifecycles may change. Ensure compatibility with existing board layout constraints for the 32-TQFP footprint before procurement.

Clock Buffers, Drivers Selection Notes

Select this component when a single clock source must drive up to 18 loads with minimal skew. Verify that the system power supply falls within the 2.375V to 3.465V range. Confirm that the required input signal format matches the supported LVCMOS, LVPECL, or LVTTL standards.

Clock Buffers, Drivers Part Context

This part belongs to the Cypress clock buffer family designed for robust signal distribution. It integrates buffering and multiplexing capabilities to simplify clock tree design in complex digital systems.

Clock Buffers, Drivers Replacement Considerations

Check for direct pin-compatible substitutes from Infineon or Cypress with identical 1:18 ratios and 200MHz performance. Verify electrical parameters match exactly if cross-referencing other series.
