SI5338A-B05495-GMR

Overview

The SI5338A-B05495-GMR 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 of 1.8 V, 2.5 V, or 3.3 V and accepts inputs up to 710 MHz. Key electrical parameters include a typical RMS jitter of 0.7 ps, a maximum output frequency of 710 MHz for differential outputs, and an operating temperature range of -40 °C to +85 °C.

Feature Summary

• MultiSynth™ technology enables independent, zero ppm precision frequency synthesis on four outputs.
• Supports flexible input references: external crystals (8-30 MHz), CMOS (5-200 MHz), and differential inputs (up to 710 MHz).
• Configurable output drivers support various signal formats and independent voltage levels (1.5, 1.8, 2.5, or 3.3 V).
• Features glitchless frequency adjustments in 1 ppm steps and independent phase adjustment with <20 ps accuracy.

Applications

• PCIe Gen 1/2/3/4 Common Clock and Gen 3 SRNS compliant systems.
• Ethernet switch/router and 1 GbE/10 GbE networking equipment.
• Processor and FPGA clocking solutions.
• Broadcast video/audio timing infrastructure.

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm package type and tape/reel specifications. Ensure compatibility with I2C/SMBus interface requirements and check for moisture sensitivity handling instructions during storage and assembly.

Selection Notes

Select this component when low-jitter (<1 ps RMS) multi-frequency generation is required. Confirm that the target application supports the available output formats (LVPECL, LVDS, etc.) and that the input reference frequency falls within the supported ranges. Verify power supply constraints align with the 1.8 V, 2.5 V, or 3.3 V core options.

Part Context

This part belongs to the Si5338 family of high-performance clock generators. It is designed to replace multiple discrete crystal oscillators by providing four independent clock signals from a single source. The device integrates NVM programming capabilities for configuration retention.

Replacement Considerations

Consult official Skyworks documentation for verified cross-reference part numbers. Ensure any substitute maintains the same QFN-24 package dimensions and pinout compatibility.
