SI5338M-B05847-GM

Overview

The SI5338M-B05847-GM is a programmable quad clock generator from Skyworks Solutions, utilizing MultiSynth technology to synthesize any frequency on four independent output drivers. It supports differential and single-ended formats including LVPECL, LVDS, CML, HCSL, CMOS, SSTL, and HSTL. The device operates with a core supply voltage of 1.8 V, 2.5 V, or 3.3 V and accepts input references up to 710 MHz. Key electrical parameters include a typical phase jitter of 0.7 ps RMS, a maximum output frequency of 710 MHz for differential outputs, and an operating temperature range of -40 °C to +85 °C.

Feature Summary

• I2C/SMBus programmable interface for flexible configuration
• Low phase jitter performance of 0.7 ps RMS typical
• Independent output voltage control (1.5, 1.8, 2.5, or 3.3 V) per driver
• Glitchless frequency adjustment via independent increment/decrement features

Applications

• PCIe Gen 1/2/3/4 common clock and SRNS compliance
• Ethernet switch and router timing
• Processor and FPGA clocking
• Broadcast video/audio timing systems

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm package type and shipping configuration. Ensure compatibility with I2C bus voltage levels if operating below 2.5 V by checking register settings. Confirm that the required frequency synthesis matches the device's MultiSynth capabilities before procurement.

Selection Notes

Select this component when multiple independent clock frequencies are required from a single source. Verify that the target output signal format (LVPECL, LVDS, etc.) and voltage levels match the load requirements. Consider the input reference frequency range and ensure the desired output jitter specifications fall within the device's typical performance metrics.

Part Context

This part belongs to the Si5338 family of high-performance clock generators. The 'M' suffix typically denotes a specific factory-programmed configuration variant within the series. The device replaces multiple discrete crystal oscillators, reducing board space and power consumption in complex digital systems requiring precise timing.

Replacement Considerations

Direct pin-to-pin replacements within the same family may require reprogramming via ClockBuilder Pro software. Verify that alternative SKUs support the same output formats and voltage levels. Check for any changes in the I2C address or register map if substituting with different suffix variants.
