SI5338Q-B05298-GM

Application Specific Clock/Timing Overview

The SI5338Q-B05298-GM is a programmable quad clock generator from Skyworks Solutions. It utilizes MultiSynth technology to synthesize any frequency on four independent output drivers with zero ppm precision. The device supports differential and single-ended outputs, including LVPECL, LVDS, CML, HCSL, CMOS, SSTL, and HSTL formats. Key electrical parameters include a maximum output frequency of 710 MHz for differential signals and 200 MHz for CMOS. It operates on a single core supply of 1.8 V, 2.5 V, or 3.3 V, with typical current consumption of 45 mA. The component features low phase jitter of 0.7 ps RMS and is housed in a 24-lead QFN package.

Application Specific Clock/Timing Feature Summary

• MultiSynth technology enables independent, any-frequency synthesis on four output drivers with true zero ppm accuracy.
• Supports flexible input references including external crystals (8–30 MHz), CMOS (5–200 MHz), and differential inputs (up to 710 MHz).
• Configurable output drivers support multiple signal formats: LVPECL, LVDS, CML, HCSL, CMOS, SSTL, and HSTL.
• Features glitchless frequency adjustments in 1 ppm steps and independent phase adjustment with <20 ps accuracy.

Application Specific Clock/Timing Applications

• PCIe Gen 1/2/3/4 Common Clock and Gen 3 SRNS compliant systems
• Ethernet switch/router timing
• Processor and FPGA clocking
• Broadcast video/audio timing
• Telecom line cards

Application Specific Clock/Timing Procurement Notes

Verify the specific factory programming configuration associated with the B05298 suffix against the system requirements. Confirm that the I2C/SMBus interface voltage levels match the target bus specifications. Ensure ESD protection measures are adequate given the device's sensitivity. Check for moisture sensitivity level requirements during storage and handling.

Application Specific Clock/Timing Selection Notes

Select this component when independent frequency synthesis across four outputs is required. Ensure the desired output format (LVPECL, LVDS, etc.) and frequency range fall within the specified limits. Verify that the available input reference source matches the supported types. Consider the thermal characteristics and PCB land pattern for the 4x4 mm QFN package.

Application Specific Clock/Timing Part Context

This part belongs to the Si5338 family of I2C-programmable clock generators. The 'Q' suffix typically denotes automotive qualification standards, while 'B05298' indicates a specific factory-programmed configuration. The '-GM' suffix refers to the tape and reel packaging option.

Application Specific Clock/Timing Replacement Considerations

Direct replacements must be from the Si5338 family with compatible pinouts and electrical characteristics. Verify that alternative part numbers support the same output formats and frequencies. Cross-reference the factory programming configuration if using a blank Si5338 device.
