SI5338N-B06174-GM

Overview

The Skyworks SI5338N-B06174-GM is a programmable quad clock generator utilizing MultiSynth technology. It synthesizes four independent clocks with 0 ppm precision, supporting frequencies up to 710 MHz on differential outputs (LVPECL/LVDS/CML) and lower limits for single-ended formats. The device features low phase jitter of 0.7 ps RMS typical, configurable spread spectrum modulation, and independent glitchless frequency/phase adjustments. It operates from a single core supply of 1.8 V, 2.5 V, or 3.3 V within an industrial temperature range of –40 °C to +85 °C.

Feature Summary

• I2C-programmable synthesis with true zero ppm accuracy across all outputs
• Four independent output drivers supporting LVPECL, LVDS, CML, HCSL, CMOS, SSTL, and HSTL formats
• Low phase jitter performance of 0.7 ps RMS typical
• Independent frequency increment/decrement and phase adjustment capabilities

Applications

• PCIe Gen 1/2/3/4 common clock and SRNS compliant systems
• Ethernet switch and router timing
• FPGA and processor clocking solutions
• Broadcast video and audio timing distribution

Procurement Notes

Verify the specific factory-programmed NVM configuration associated with the B06174 suffix against system requirements. Confirm that the QFN-24 package land pattern matches the recommended PCB layout in the datasheet. Ensure I2C pull-up voltages are compatible with the selected core supply voltage.

Selection Notes

Select this component when independent any-frequency synthesis is required for multiple domains. Validate input reference compatibility, as the device supports external crystals (8–30 MHz), CMOS, SSTL/HSTL, and differential inputs up to 710 MHz. Check output driver voltage requirements, which can be independently set to 1.5 V, 1.8 V, 2.5 V, or 3.3 V.

Part Context

This part belongs to the Si5338 family of I2C-programmable clock generators. The 'N' suffix indicates a custom factory-programmed Non-Volatile Memory (NVM) configuration, while 'B06174' specifies the unique frequency plan. The '-GM' suffix denotes the 24-lead QFN package variant.

Replacement Considerations

Direct pin-to-pin replacements within the same family include other Si5338 variants with different NVM configurations (e.g., SI5338N-Bxxxxx-GM). Verify that alternative parts support the required output frequencies and signal formats.
