SI52112-A2-GTR

Overview

The SI52112-A2-GTR 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 without termination resistors. The device features a triangular spread spectrum profile for EMI reduction and operates on a 3.3 V supply with an operating current of 17 mA. It is housed in an 8-pin TSSOP package and supports extended temperature ranges from -40 to +85 °C.

Feature Summary

• PCIe Gen 1 compliant with low power HCSL differential output buffers
• Supports Serial-ATA (SATA) at 100 MHz without termination resistors
• Triangular spread spectrum profile for maximum EMI reduction
• Accepts 25 MHz crystal input or clock input

Applications

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

Procurement Notes

Verify the component status before procurement as this part number may be subject to discontinuation notices. Confirm that the 8-pin TSSOP tape and reel packaging aligns with manufacturing requirements. Ensure compatibility with the specified 3.3 V supply voltage and extended temperature range during final validation.

Selection Notes

Select the SI52112-A2-GTR for designs requiring PCIe Gen 1 compliance with spread spectrum capabilities. For applications needing PCIe Gen 2 support, consider the Si52112-B3/B4 series. For PCIe Gen 3 requirements, refer to the Si52112-B5/B6 series. Ensure the design accommodates the 8-pin TSSOP footprint and 3.3 V power supply constraints.

Part Context

This component belongs to the Si52112-A1/A2 family of PCI-E Xpress Gen 1 dual output clock generators. The 'A2' designation indicates support for 0.5% down spread outputs, distinguishing it from the non-spread Si52112-A1 variant. The 'GTR' suffix specifies the 8-pin TSSOP package configuration supplied in tape and reel format.

Replacement Considerations

For discontinued A-series parts, Skyworks recommends the Si52112-B6-GT as a replacement. Verify pinout and electrical specifications against the new part number datasheet before implementation.
