SI52112-A2-GM2

Overview

The SI52112-A2-GM2 is a PCIe Gen 1 dual-output clock generator from Skyworks Solutions. It sources two differential HCSL clocks from a 25 MHz crystal or clock input, supporting Serial-ATA at 100 MHz. The device features a triangular spread spectrum profile with -0.5% down-spread for EMI reduction. Operating on a 3.3 V supply (2.97 V to 3.63 V), it draws 17 mA and operates within an extended temperature range of –40 °C to +85 °C. It utilizes a 10-pin TDFN package measuring 3x3 mm.

Feature Summary

• PCIe Gen 1 compliant with two differential HCSL outputs
• -0.5% triangular spread spectrum for EMI reduction
• Supports 25 MHz crystal or clock input
• No termination resistors required

Applications

• Network Attached Storage
• Multi-function Printer
• Wireless Access Point
• Routers

Procurement Notes

Verify the component status before procurement as the SI52112-A2-GM2 has been marked as End-of-Life by the manufacturer. Confirm availability through authorized distributors and check for recommended replacement part numbers such as the SI52112-B6 series if continued production is required.

Selection Notes

Select the SI52112-A2-GM2 for designs requiring PCIe Gen 1 compliance with spread spectrum capabilities. Ensure the design accommodates the 10-pin TDFN footprint. For applications needing higher generation support, consider the B-series variants like the SI52112-B3 or B6.

Part Context

This component belongs to the Si52112-A1/A2 family of PCI-Express Gen 1 dual output clock generators. The 'A2' suffix specifically denotes the inclusion of -0.5% spread spectrum functionality, distinguishing it from the non-spectrum A1 variant. The 'GM2' suffix indicates the 10-pin TDFN package configuration.

Replacement Considerations

Skyworks recommends the SI52112-B6-GT as a replacement for the discontinued SI52112-A2-GT. Verify pinout compatibility and electrical specifications when transitioning to newer generations.
