CY24292LFXIT

Application Specific Clock/Timing Overview

The CY24292LFXIT is a four-output PCI-Express clock generator manufactured by Infineon Technologies. It accepts a 25 MHz crystal or clock input and synthesizes four differential 100 MHz PCI-Express clocks with HCSL-compatible output levels, alongside one single-ended 25 MHz LVCMOS output. The device incorporates spread spectrum modulation on all 100 MHz outputs to reduce electromagnetic interference (EMI). It operates within a supply voltage range of 3.0 V to 3.6 V and supports an industrial temperature range of -40°C to 85°C. Configuration is managed via an SMBus serial interface.

Application Specific Clock/Timing Feature Summary

• Four differential 100 MHz PCI-Express outputs with HCSL compatibility

• High-speed digital interface timing
• Electromagnetic interference (EMI) mitigation in PCIe designs

Application Specific Clock/Timing Procurement Notes

Verify the suffix 'IT' indicates tape and reel packaging and industrial temperature grade (-40°C to 85°C). Confirm the 'F' suffix denotes field programmability. Ensure the source document matches part number CY24292LFXIT. Check for lead-free status as specified in ordering information.

Application Specific Clock/Timing Selection Notes

Select this component when designing PCI-Express systems requiring four differential 100 MHz clocks and one 25 MHz reference. Choose the Industrial grade variant for environments operating between -40°C and 85°C. Consider the field-programmable nature if custom spread spectrum profiles are needed beyond default settings. Verify power supply stability within the 3.0 V to 3.6 V range.

Application Specific Clock/Timing Part Context

The CY24292LFXIT belongs to the CY24292 family of clock generators originally developed by Cypress Semiconductor, now part of Infineon Technologies. This specific model is designed for PCI-Express applications, providing precise clock distribution with spread spectrum features. It complements other timing solutions by offering integrated PLL synthesis and configurable outputs in a compact 32-pin QFN package.
