CY28411OXC-1

Application Specific Clock/Timing Overview

The CY28411OXC-1 is a clock generator designed for Intel Alviso chipset and Pentium-M CPU applications. It operates on a 3.3V supply (3.135V to 3.465V) within a commercial temperature range of 0°C to 85°C. The device features two PLLs and supports selectable CPU frequencies up to 266MHz via FS_A, FS_B, and FS_C inputs. Outputs include differential CPU and SRC clock pairs, fixed 96MHz dot clocks, 48MHz USB clocks, and 33MHz PCI clocks. It utilizes a 56-pin SSOP package and includes I2C support for configuration.

Application Specific Clock/Timing Procurement Notes

Verify the specific suffix 'OXC' against official Infineon/Cypress documentation to confirm package type and RoHS status. Ensure the source component matches the CY28411-1 functional specifications. Confirm that the 56-pin SSOP package aligns with board layout requirements.

Application Specific Clock/Timing Selection Notes

Select this component for designs requiring Intel CK410M compliance. Verify that the required CPU frequency (e.g., 100MHz, 133MHz, 266MHz) matches the FS pin configurations. Ensure the system design accommodates the 3.3V power supply and 56-pin SSOP footprint.

Application Specific Clock/Timing Part Context

This part belongs to the CY28411 family of clock generators originally manufactured by Cypress Semiconductor Corporation, now part of Infineon Technologies. It is specifically engineered for mobile processor clocking solutions, providing multiple synchronized output clocks from a single crystal input.

Application Specific Clock/Timing Replacement Considerations

Direct replacements must match the CY28411-1 functionality and 56-pin SSOP package. Verify compatibility with Intel CK410M specifications if used in certified designs.
