SI52202-A02BGMR

Overview

The Skyworks SI52202-A02BGMR is a two-output PCI Express clock generator supporting Gen 1 through Gen 7 specifications. It provides two 100 MHz differential LP-HCSL outputs compliant with common clock and SRIS architectures. The device operates on a 1.5 V to 1.8 V supply with separate VDD and VDD_IO rails. Key electrical parameters include a maximum RMS jitter of 0.085 ps, an operating temperature range of –40 °C to +85 °C, and a 20-pin QFN (3 x 3 mm) package. It accepts a 25 MHz crystal or clock input and features internal 85 Ω line matching.

Feature Summary

• Two-output PCIe Gen 1/2/3/4/5/6/7 clock generator with LP-HCSL drivers
• Low jitter performance of 0.085 ps (RMS) max for PCIe Gen 6 compliance
• Internal 85 Ω impedance matching eliminates external resistors
• Hardware control pins and I2C support for output enable, spread spectrum, and frequency select

Applications

• Servers
• Storage systems
• Data centers
• PCIe add-on cards
• Network Interface Cards (NICs)

Procurement Notes

Verify the specific ordering suffix 'A02BGMR' against the manufacturer's current documentation to confirm pinout, packaging, and configuration details. Ensure compatibility with the required 25 MHz reference input and power supply voltages before integration. Check for any product change notifications that may affect lead times or material composition.

Selection Notes

Select this component when a compact, low-power solution is required for dual-channel PCIe clocking. The Si52202 is limited to 100 MHz output frequencies unless custom configurations are arranged with the manufacturer. It is suitable for designs prioritizing board space optimization due to its small 20-pin QFN footprint.

Part Context

The SI52202 belongs to the Si522xx family, which includes the Si52212, Si52208, and Si52204. These devices share similar architectural features but differ in output count and package size. The Si52202 specifically offers the smallest form factor in the series, designed for applications requiring only two differential clock outputs.

Replacement Considerations

Direct parameter-equivalent replacements within the same family include the Si52204, Si52208, and Si52212, though these offer higher output counts and different packages. Cross-family substitution requires careful evaluation of pin compatibility and electrical specifications.
