SL28PCIE14ALC

Application Specific Clock/Timing Overview

The SL28PCIe14ALC is a low-power clock generator and fan-out buffer compliant with PCI-Express Gen 2 and Gen 3 standards. It features four differential serial reference clock outputs operating at frequencies up to 100 MHz, derived from a 25 MHz crystal or clock input. The device utilizes EProClock® non-volatile programmable technology for configuration via SMBus or hardware selection. Key electrical parameters include a 3.3V supply voltage, industrial temperature range (-40°C to 85°C), and RMS phase jitter of 3.0 ps for PCIe Gen 2. It is housed in a 32-pin QFN package.

• EProClock® Non-Volatile Programmable Technology
• SMBus Interface with Readback Capabilities

Application Specific Clock/Timing Applications

• PCI-Express Gen 2 & Gen 3 Clock Generation
• Intel Ultra Mobile Platform Designs
• Low Power System Clock Distribution

Application Specific Clock/Timing Procurement Notes

Verify the specific ordering suffix against the datasheet table. The 'LC' suffix indicates a commercial temperature range (0°C to 85°C). Ensure this aligns with system requirements, as other variants like 'LI' support the full industrial range (-40°C to 85°C). Confirm package type and flow details directly with the manufacturer or authorized distributors.

Application Specific Clock/Timing Selection Notes

Select based on required temperature range and packaging format. The SL28PCIe14ALC is the commercial tape-and-reel variant. For industrial temperature applications, consider the SL28PCIe14ALI or ALIT. Verify that the 25MHz input requirement and 3.3V supply voltage match the target board design constraints.

Application Specific Clock/Timing Part Context

This component belongs to the Skyworks SL28PCIe14 family of low-power clock generators. It is specifically designed for Intel Ultra Mobile Platforms. The part number structure includes suffixes indicating temperature range and packaging, such as 'A' for lead-free, 'L' for QFN package, and 'C' or 'I' for commercial or industrial temperature grades.
