SI52112-B5-GTR

Overview

The SI52112-B5-GTR is a PCIe Gen 3 dual-output clock generator manufactured by Skyworks Solutions, Inc. It sources two compliant clocks from a 25 MHz crystal or clock input. The device features low power HCSL differential output buffers and supports Serial-ATA at 100 MHz without requiring termination resistors. It operates on a 3.3 V supply with a maximum current of 17 mA. The component utilizes an 8-pin TSSOP package in tape-and-reel format for automated assembly.

Feature Summary

• PCIe Gen 1, Gen 2, and Gen 3 common clock compliant
• Gen 3 SRNS compliant
• Low power HCSL differential output buffers
• No termination resistors required

Applications

• Network attached storage
• Multi-function printer
• PCIe Add-on Cards
• Network Interface Cards
• Wireless access point

Procurement Notes

Verify the ordering suffix 'GTR' corresponds to the 8-pin TSSOP package type and tape-and-reel packaging configuration as specified in the manufacturer's ordering guide. Confirm that the specific revision level matches the design requirements, noting that product information is subject to change without notice.

Selection Notes

Select this part when spread spectrum functionality is not required, as the B5 variant does not support it. Ensure the application fits within the extended temperature range of –40 to 85 °C. Verify that the 8-pin TSSOP footprint aligns with the PCB layout constraints compared to the available TDFN options.

Part Context

This component belongs to the Si52112-B5/B6 family of high-performance PCIe clock generators. The B5 designation specifically indicates the absence of spread spectrum outputs, distinguishing it from the B6 variant which supports 0.5% down spread. Both variants share identical electrical specifications and compliance standards.
