SI52147-A01AGMR

Overview

The SI52147-A01AGMR is a nine-output PCIe clock generator from Skyworks Solutions, packaged in a 48-pin QFN. It sources clocks compliant with PCIe Gen 1, Gen 2, Gen 3, and Gen 4 common clock specifications from a single 25 MHz crystal or clock input. The device provides low-power push-pull HCSL compatible differential outputs without requiring external termination resistors. Operating on a 3.3 V supply, it features six hardware output enable pins, an I2C interface for configuration, and a spread spectrum control pin for EMI reduction. It supports industrial temperatures ranging from -40°C to +85°C.

Feature Summary

• Nine differential HCSL-compatible outputs compliant with PCIe Gen 1 through Gen 4 common clock standards
• Supports 25 MHz crystal or clock input with triangular spread spectrum profile for EMI reduction
• Includes six hardware output enable pins and I2C interface with readback capabilities
• Operates at 3.3 V with dynamic supply current of 85 mA and industrial temperature range (-40°C to +85°C)

Applications

• Network attached storage (NAS)
• Multi-function printers
• Wireless access points
• Servers

Procurement Notes

Verify the 'R' suffix indicates tape and reel packaging rather than tray. Confirm the specific revision code via the I2C register if required for system compatibility. Ensure the design accounts for the 48-pin QFN land pattern dimensions specified in the datasheet. Check for moisture sensitivity handling requirements during assembly.

Selection Notes

Select this component when nine synchronized PCIe clocks are required from a single reference. It is suitable for designs needing low jitter performance across multiple generations of PCIe standards. Consider the I2C configuration flexibility if dynamic output enabling is necessary. Verify that the 3.3 V power supply rail meets the specified operating voltage range of 3.135 V to 3.465 V.

Part Context

The SI52147-A01AGMR belongs to the Si52147 family of high-performance PCIe clock generators. It shares functional similarities with other members like the SI52144 and SI52146 but offers a higher output count. The 'A01AGM' variant denotes the standard tray package, while the 'R' suffix specifies tape and reel packaging for automated assembly.
