SI52112-A4-GM2

Overview

The SI52112-A4-GM2 is a dual-output PCI Express clock generator manufactured by Skyworks Solutions Inc. It operates within a supply voltage range of 3.13 V to 3.46 V and supports a maximum output frequency of 100 MHz with a maximum input frequency of 25 MHz. The device is housed in a compact 10-TDFN package measuring 3x3 mm. It features an operating temperature range from -40°C to +85°C and includes an integrated PLL for precise clock generation.

Feature Summary

• Dual-output architecture designed specifically for PCI Express applications
• Compact 10-TDFN surface-mount package for space-constrained designs
• Integrated phase-locked loop for stable clock signal generation

Applications

• PCI Express Gen 1 systems requiring dual differential outputs
• High-performance computing platforms needing low-jitter timing
• Telecommunications infrastructure equipment

Procurement Notes

Verify the specific suffix GM2 against official Skyworks documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with existing PCB footprints, as the 10-TDFN form factor differs from standard TSSOP variants. Cross-reference RoHS compliance status and moisture sensitivity levels prior to procurement to meet assembly requirements.

Selection Notes

Select this component when a small footprint is critical for dual-output PCIe clocking. Compare electrical parameters such as jitter performance and power consumption against alternative packages like TSSOP. Confirm that the 100 MHz maximum frequency meets system bandwidth requirements and that the operating temperature range aligns with environmental conditions.
