SI52112-B5-GM3R

Overview

The SI52112-B5-GM3R is a two-output PCIe clock generator manufactured by Skyworks Solutions Inc. It operates within a supply voltage range of 3.13 V to 3.46 V and draws a typical operating current of 17 mA. The device supports a maximum output frequency of 100 MHz with a maximum input frequency of 25 MHz. It features a jitter specification of 250 ps and maintains a duty cycle of up to 55%. Designed for surface-mount applications, it utilizes a TDFN-8 package and functions reliably across an industrial temperature range from -40°C to +85°C.

Feature Summary

• Two-output configuration optimized for PCIe clock generation
• Low jitter performance specified at 250 ps
• Operates on a 3.3 V nominal supply (3.13 V to 3.46 V range)
• Available in compact TDFN-8 surface-mount package

Applications

• PCI Express (PCIe) system clock distribution
• Server and storage motherboard timing solutions
• Industrial computing hardware requiring precise clock synchronization

Procurement Notes

Verify the specific suffix 'GM3R' against official Skyworks documentation to confirm reel packaging quantities and tape-and-reel specifications. Ensure compatibility with existing PCB footprints for the TDFN-8 package during sourcing. Cross-reference the manufacturer part number with authorized distributors to validate authenticity and traceability before procurement.

Selection Notes

Select this component when a dual-output PCIe clock solution with low jitter is required. Confirm that the 100 MHz maximum output frequency meets system requirements. Verify that the TDFN-8 package dimensions fit the design constraints. Ensure the operating temperature range of -40°C to +85°C aligns with the environmental conditions of the target application.

Part Context

This part belongs to the SI52112 series of TinyClock PCIe clock generators. The series includes variants with different output counts and packages, such as the SI52112-A2 and SI52112-B6 models. The B5 variant specifically denotes a two-output configuration designed for standard PCIe timing applications within the Skyworks portfolio.

Replacement Considerations

Skyworks recommends the SI52112-B6-GT as a replacement for related discontinued models in the A2 series.
