SI53212-A02AGM

Overview

The Skyworks SI53212-A02AGM is a 12-output PCIe clock fanout buffer supporting Gen 1 through Gen 6 specifications. It operates on a single 1.5 V to 1.8 V supply and accepts input frequencies from 10 MHz to 200 MHz. The device provides low-power, push-pull HCSL-compatible differential outputs with an internal 100 Ω or 85 Ω impedance matching option. Key electrical parameters include a maximum additive jitter of 0.02 ps rms for Gen 6 compliance and a typical dynamic supply current of 74 mA at 1.8 V with all outputs enabled.

Feature Summary

• 12-output 100 MHz compliant clock fanout buffer for PCIe Gen 1 through Gen 6
• Low additive jitter of 0.02 ps rms max to meet Gen 6 specifications
• Individual hardware control pins and I2C controls for output enable
• Spread spectrum tolerant to pass through spread input clocks for EMI reduction

Applications

• Data centers
• Servers
• Storage systems
• PCIe add-on cards
• Communications equipment

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and impedance settings. Confirm RoHS-6 compliance status and lead times directly with authorized distributors or the manufacturer before placing orders.

Selection Notes

Select this component when a high-density 12-channel distribution solution is required for modern PCIe architectures. Ensure the design supports the 1.5 V to 1.8 V power domain and utilizes the 64-pin QFN (9 x 9 mm) footprint. Consider the adjustable slew rate feature if signal integrity optimization is needed for specific board layouts.

Part Context

This part belongs to the Si532xx family, which includes the Si53208 (8-output) and Si53204 (4-output) variants. All members share identical functional blocks and electrical characteristics but differ in output count and physical package size to accommodate various density requirements.

Replacement Considerations

The Si53208 and Si53204 are functionally similar within the same family but offer fewer outputs. Verify pin compatibility and thermal performance if substituting with lower-output variants.
