IMIB9940LBL

Clock Buffers, Drivers Overview

The IMIB9940LBL 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 LVCMOS, LVPECL, and LVTTL input signals. The device operates with a maximum frequency of 200 MHz and requires dual voltage supplies of 2.375V–2.625V and 3.135V–3.465V. Packaged in a 32-TQFP (7x7) surface-mount case, it functions within an operating temperature range of -40°C to 85°C.

Clock Buffers, Drivers Procurement Notes

Verify the manufacturer part number against official Cypress or Infineon documentation, as this specific suffix may be a distributor-specific code. Confirm the package type is 32-TQFP and check for end-of-life status before procurement.

Clock Buffers, Drivers Selection Notes

Select this component when a 2:18 fanout buffer is required for LVCMOS, LVPECL, or LVTTL signals up to 200 MHz. Ensure the design accommodates the dual voltage supply requirements and the 32-TQFP footprint.

Clock Buffers, Drivers Part Context

Cypress Semiconductor was acquired by Infineon Technologies in 2020. This component belongs to the clock buffer family, which provides signal integrity and timing distribution for high-speed digital circuits.

Clock Buffers, Drivers Replacement Considerations

Check for direct pin-compatible replacements from Infineon's current portfolio. Verify electrical parameters such as propagation delay and output drive strength if substituting with other vendors.
