CY2XL11ZXI

Clock Generators, PLLs, Frequency Synthesizers Overview

The CY2XL11ZXI is a Phase Locked Loop (PLL) based high-performance clock generator manufactured by Cypress Semiconductor Corp. It features a crystal oscillator interface and one LVDS output pair, optimized for generating PCI Express, Fibre Channel, and other high-performance clock frequencies. The device produces an output frequency that is four times the crystal frequency. It utilizes low noise VCO technology to achieve less than 1 ps typical RMS phase jitter. The component operates at 3.3V or 2.5V supply voltages and is housed in an 8-pin TSSOP package.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific suffix 'ZI' against official datasheets to confirm temperature range and packaging details. Ensure the ordering part number matches the required supply voltage and output configuration. Cross-reference with manufacturer documentation to validate RoHS compliance and lead-free status before procurement.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when low jitter performance is critical for high-speed serial interfaces like PCIe or FC. Consider the single LVDS output capability and the requirement for an external crystal. Verify that the 4x multiplication factor aligns with the target system clock frequency requirements.

Clock Generators, PLLs, Frequency Synthesizers Part Context

The CY2XL11 belongs to the CY2XL11 family of low-noise LVDS clock generators. This series is designed for applications requiring precise clocking with minimal jitter. The ZXI suffix typically denotes specific packaging and temperature grade variations within the broader CY2XL11 product line.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Check for CY2XL11 variants with different suffixes for alternative temperature ranges or packages. Other Cypress PLL-based clock generators may serve as functional substitutes if pin compatibility and jitter specifications are met.
