SI5338N-B06176-GMR

Overview

The SI5338N-B06176-GMR is a programmable quad clock generator from Skyworks Solutions. It synthesizes four independent output clocks with zero ppm frequency accuracy using MultiSynth technology. The device supports differential and single-ended outputs, including LVPECL, LVDS, HCSL, CMOS, SSTL, and HSTL formats. It operates on a single core supply of 1.8 V, 2.5 V, or 3.3 V, with individual output drivers configurable for 1.5 V, 1.8 V, 2.5 V, or 3.3 V. Key electrical parameters include a maximum input frequency of 710 MHz, a typical phase jitter of 0.7 ps RMS, and an operating temperature range of -40 to +85 °C.

Feature Summary

• MultiSynth technology enables any-frequency synthesis with 0 ppm precision on four independent outputs.
• Flexible output configurations support up to four differential or eight single-ended clocks in mixed combinations.
• Low phase jitter performance of 0.7 ps RMS typ, compliant with PCIe Gen 1/2/3/4 standards.
• Programmable via I2C/SMBus interface with features for glitchless frequency adjustment and spread spectrum.

Applications

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

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm pinout and configuration details. Ensure compatibility with the intended I2C bus voltage levels (1.71 V to 3.63 V) and check for moisture sensitivity handling requirements during storage and assembly.

Selection Notes

Select this component when low jitter (< 1 ps RMS) and high flexibility in output formats are required. Confirm that the desired output frequencies fall within the supported ranges for the chosen signal format (e.g., LVDS up to 710 MHz, CMOS up to 200 MHz). Verify power supply constraints for both the core and individual output drivers.

Part Context

This part belongs to the Si5338 family of I2C-programmable clock generators. It replaces multiple discrete crystal oscillators by providing synthesized clocks with precise frequency control. The device integrates a PLL and MultiSynth dividers to generate independent frequencies from a single reference input.

Replacement Considerations

Direct replacements within the same package and functionality require checking the specific factory programming code in the suffix. Other Si533x variants may offer different output counts or jitter specifications but require verification of register compatibility and pin assignments.
