CY29940AXIT

Clock Buffers, Drivers Overview

The CY29940AXIT is a clock buffer and distribution integrated circuit manufactured by Infineon Technologies. It functions as a fanout buffer or multiplexer with a 1:18 input-to-output ratio, supporting a maximum frequency of 200 MHz. The device operates within a supply voltage range of 2.375 V to 3.465 V and supports LVCMOS, LVPECL, and LVTTL input types, while providing LVCMOS and LVTTL outputs. It is housed in a 32-LQFP package (32-TQFP, 7x7 mm) designed for surface mount installation. The component is rated for an industrial operating temperature range of -40°C to +85°C.

Clock Buffers, Drivers Procurement Notes

Verify the current lifecycle status, as the component may be discontinued or subject to limited availability. Confirm that the 32-LQFP package dimensions match the target PCB footprint. Ensure the design accommodates the specified 2.375 V to 3.465 V supply voltage range and industrial temperature constraints.

Clock Buffers, Drivers Selection Notes

Select this component when a single clock source must drive up to 18 synchronous loads. Verify compatibility between the system's input signal standards (LVCMOS, LVPECL, or LVTTL) and the IC's input requirements. Ensure the power supply rails remain within the 2.375 V to 3.465 V window during all operating conditions.

Clock Buffers, Drivers Part Context

This part belongs to the clock driver and distribution category from Infineon Technologies. It serves as a specialized buffer for synchronizing digital circuits, distinct from general-purpose logic buffers due to its specific timing characteristics and high fanout capability.

Clock Buffers, Drivers Replacement Considerations

Check for direct pin-compatible substitutes within the same family. Verify if alternative packages or updated series offer equivalent 1:18 ratios and 200 MHz performance without altering the board layout.
