SI52112-A3-GM2

Overview

The SI52112-A3-GM2 is a dual-output PCIe Gen 1 clock generator manufactured by Skyworks Solutions Inc. It operates with a maximum output frequency of 100 MHz and accepts an input frequency up to 25 MHz. The device utilizes an 8-TSSOP package and supports HCSL output types. Key electrical specifications include a supply voltage range of 2.97 V to 3.63 V, a maximum duty cycle of 55%, and a typical jitter of 250 ps. The component functions within a temperature range of -40°C to +85°C and draws a working power current of 17 mA.

Feature Summary

• Generates dual differential outputs for PCIe applications
• Integrates a phase-locked loop (PLL) for clock synthesis
• Supports spread spectrum modulation capabilities

Applications

• PCI Express Gen 1 system designs
• Motherboard clock distribution networks
• Peripheral card timing solutions

Procurement Notes

Verify the specific suffix 'GM2' against the manufacturer's official documentation to confirm the exact package type and tape-and-reel configuration. Ensure that the required output frequencies and jitter specifications align with the target design requirements before procurement. Cross-reference the RoHS compliance status and lead times directly with authorized distributors or the manufacturer.

Selection Notes

Select this component when designing systems requiring dual differential clocks for PCIe Gen 1 interfaces. Consider the 8-TSSOP package size for board space constraints. Verify that the 100 MHz maximum output frequency meets the system's bandwidth needs. Evaluate the 250 ps jitter performance against the signal integrity requirements of the connected components.

Part Context

This part belongs to the SI52112 series of clock generators designed specifically for PCI Express applications. The series provides flexible clocking solutions for various PCIe generations. The A3 variant typically denotes specific factory programming or feature sets defined by Skyworks Solutions Inc. for dual-output configurations.

Replacement Considerations

Skyworks recommends the SI52112-B6-GT as a replacement for the discontinued SI52112-A2-GT. For the SI52112-A3-GM2, verify compatibility with newer B-series variants such as the SI52112-B5-GT or SI52112-B6-GT through official datasheets.
