SI52112-A1-GM2R

Overview

The SI52112-A1-GM2R 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, operating at frequencies up to 100 MHz. The device features a 10-pin TDFN (3x3 mm) package and operates on a 3.3 V supply with a typical current of 17 mA. Unlike the A2 variant, the A1 model does not support spread spectrum outputs. It supports Serial-ATA at 100 MHz without requiring termination resistors.

Feature Summary

• PCIe Gen 1 compliant dual-output clock generation
• Low power consumption with 17 mA typical operating current
• HCSL differential output buffers requiring no termination resistors
• Supports 25 MHz crystal or clock input

Applications

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

Procurement Notes

Verify component authenticity through authorized distributors. Confirm RoHS compliance status via official documentation. Check for end-of-life notices as availability may be restricted. Ensure ordering suffixes match required packaging specifications.

Selection Notes

Select this model over the A2 variant if spread spectrum functionality is not required. Verify that the application requires only PCIe Gen 1 compliance rather than Gen 2 or Gen 3 standards. Ensure the design accommodates the 10-pin TDFN footprint.

Part Context

This component belongs to the Si52112-A1/A2 family designed for consumer and embedded applications. It serves as a low-power alternative to larger clock generators, utilizing a compact 3x3 mm package suitable for space-constrained designs.

Replacement Considerations

For PCIe Gen 2 applications, consider the Si52112-B3/B4 series. For PCIe Gen 3 applications, refer to the Si52112-B5/B6 series. Single-output requirements may utilize the Si52111 series.
