CY7B9945V-2AXIT

Clock Generators, PLLs, Frequency Synthesizers Overview

The CY7B9945V-2AXIT is a high-speed multi-phase PLL clock buffer from the RoboClock series, manufactured by Infineon Technologies. It operates on a single 3.3 V supply and supports input frequencies ranging from 24 MHz to 200 MHz. The device provides ten true outputs for clock distribution within a specified output frequency range of 24 MHz to 200 MHz. Designed for surface-mount installation, it is housed in a lead-free TQFP-52 package measuring 10 x 10 mm with a height of 1.40 mm. The component functions within an industrial temperature range of -40°C to +85°C and utilizes silicon technology.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific suffix 'T' against official documentation to confirm tape-and-reel packaging details, as generic listings may not specify this. Confirm RoHS compliance status through current datasheets. Check for end-of-life notifications or obsolescence notices from Infineon, as availability may be restricted. Ensure the supplier provides valid traceability documents for the silicon manufacturer.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when a single-supply 3.3 V PLL-based clock buffer with ten outputs is required. Verify that the operating temperature range of -40°C to +85°C meets system environmental constraints. Ensure the input frequency falls within the 24 MHz to 200 MHz specification. Compare pinout compatibility if replacing existing designs using the standard TQFP-52 footprint.
