CY28400ZXC-2

Application Specific Clock/Timing Overview

The CY28400ZXC-2 is a clock buffer integrated circuit manufactured by Skyworks Solutions, Inc. It functions as a differential buffer designed for high-speed serial interface applications, specifically supporting PCI Express and SATA standards. The device operates with a maximum output frequency of 100 MHz and accepts input frequencies up to 210 MHz. It requires a supply voltage range between 3.135 V and 3.465 V. The component is housed in an SSOP-28 package and is rated for commercial operating temperatures from 0°C to +70°C.

Application Specific Clock/Timing Feature Summary

• Differential buffer configuration providing one input and four outputs
• Supports PCI Express and SATA signal integrity requirements
• Operates within a 3.135 V to 3.465 V power supply range
• Maximum output frequency capability of 100 MHz

Application Specific Clock/Timing Applications

• PCI Express bus buffering
• SATA interface clock distribution
• High-speed digital system clock trees

Application Specific Clock/Timing Procurement Notes

This component is identified as End-of-Life (EOL) by the manufacturer. Availability is restricted, and distributors may not stock this item in the user's region. Verification of current lifecycle status and last-time-buy options through official Skyworks channels is required before design commitment.

Application Specific Clock/Timing Selection Notes

Select this part for legacy designs requiring a 1:4 differential fan-out buffer for PCI Express or SATA interfaces. Ensure the design accommodates the SSOP-28 package dimensions and the specific 3.135 V to 3.465 V voltage rails. Verify that the 100 MHz maximum output frequency meets the system timing requirements.

Application Specific Clock/Timing Part Context

The CY28400 series belongs to Skyworks' portfolio of clock and timer ICs. This specific model is a variant within the CY28400 family, distinguished by its ZXC-2 suffix indicating package and temperature grade specifications. It serves as a support component for chipset clock distribution in computing platforms.

Application Specific Clock/Timing Replacement Considerations

Public documentation lists SI53154-A01AGM as a potential replacement. This alternative is a PCIe Gen 1/2/3/4/5 1:4 fanout buffer. Verify pin compatibility and electrical parameter alignment before substitution.
