SI52112-A4-GT

Overview

The SI52112-A4-GT is a two-output PCIe clock generator manufactured by Skyworks Solutions Inc. It operates within a supply voltage range of 2.97 V to 3.63 V and supports maximum output frequencies up to 100 MHz with a maximum input frequency of 25 MHz. The device features low jitter performance of 250 ps and draws a typical operating current of 17 mA. It is housed in an 8-TSSOP surface-mount package and functions across an industrial temperature range from -40 °C to +85 °C, designed for high-reliability timing applications.

Feature Summary

• Two-output configuration optimized for PCI Express (PCIe) clock generation
• Low jitter specification of 250 ps for signal integrity
• Operates on a single 3.3 V supply with 17 mA typical current consumption
• Available in compact 8-TSSOP surface-mount packaging

Applications

• PCI Express Gen 1/2/3 clock distribution
• Server and storage system timing
• Industrial control boards requiring precise clocking

Procurement Notes

Verify the specific suffix 'A4' against official Skyworks documentation to confirm pinout and electrical characteristics, as variants within the SI52112 family may differ. Confirm RoHS compliance status and check for any Product Change Notices or End-of-Life announcements prior to finalizing procurement plans.

Selection Notes

Select this component when a dual-output HCSL clock source is required for PCIe interfaces. Ensure the design accommodates the 8-TSSOP footprint and that the 250 ps jitter meets the system's timing budget. Compare against the SI52112-B6 series if newer manufacturing processes or updated specifications are preferred.

Part Context

This part belongs to the SI52112 family of silicon clock generators. These devices are engineered to provide low-jitter clock signals for high-speed serial interfaces. The SI52112 series is widely used in computing and networking infrastructure where stable clocking is critical for data transmission reliability.

Replacement Considerations

Skyworks recommends the SI52112-B6-GT as a replacement for discontinued A-series variants. Verify compatibility regarding package dimensions and electrical parameters before substitution.
