SI52112-B6-GM3R

Overview

The SI52112-B6-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 supports maximum output frequencies up to 100 MHz with a maximum input frequency of 25 MHz. The device features a jitter specification of 250 ps and a maximum duty cycle of 55%. It draws a typical operating current of 17 mA and functions reliably across an extended temperature range from -40°C to +85°C. This component is packaged in a TDFN-8 form factor, designed for surface-mount applications requiring precise timing signals.

Feature Summary

• Two-output configuration optimized for PCIe clock generation
• Low jitter performance specified at 250 ps
• Operates on a single 3.3 V nominal supply (3.13 V to 3.46 V range)
• Compact TDFN-8 package suitable for space-constrained designs

Applications

• PCI Express (PCIe) system clock generation
• High-speed data transmission interfaces
• Computer motherboards and expansion cards
• Peripheral connectivity solutions

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. Cross-reference the exact part number with manufacturer databases to confirm current production status and availability channels prior to 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 align with the design layout. Ensure the operating temperature range of -40°C to +85°C satisfies environmental conditions.
