SI5338C-B05006-GM

Overview

The SI5338C-B05006-GM is a programmable quad clock generator from Skyworks Solutions, utilizing MultiSynth technology to synthesize any frequency on four independent output drivers. It supports core supply voltages of 1.8 V, 2.5 V, or 3.3 V and operates within an ambient temperature range of –40 °C to +85 °C. The device features low phase jitter of 0.7 ps RMS typical, flexible input references up to 710 MHz differential, and independently configurable outputs supporting formats such as LVPECL, LVDS, HCSL, CMOS, SSTL, and HSTL. Encased in a 4 x 4 mm QFN-24 package, it enables glitchless frequency adjustments and spread spectrum generation.

Feature Summary

• MultiSynth™ technology for zero ppm precision synthesis on four independent outputs
• Flexible input support: external crystal (8–30 MHz), CMOS (5–200 MHz), SSTL/HSTL (5–350 MHz), and differential (5–710 MHz)
• Independent output voltage configuration per driver: 1.5, 1.8, 2.5, or 3.3 V
• Glitchless frequency adjustment via independent increment/decrement feature

Applications

• PCIe Gen 1/2/3/4 common clock and SRNS compliant systems
• Ethernet switch/router and 1 GbE/10 GbE interfaces
• Processor and FPGA clocking
• Broadcast video/audio timing
• Telecom line cards and MSAN/DSLAM/PON equipment

Procurement Notes

Verify the specific factory preset configuration associated with the B05006 suffix against the official Skyworks ordering guide. Confirm that the I2C address and register map match the target system requirements before integration. Ensure ESD handling protocols are followed due to the sensitivity of the CMOS inputs and internal circuitry.

Selection Notes

Select this component when replacing multiple discrete oscillators with a single low-jitter source. Ensure the required output signal formats (LVPECL, LVDS, etc.) and frequencies fall within the specified ranges. Verify that the available input reference matches the supported types. Use ClockBuilder Pro software to generate the correct initialization file for I2C programming.

Part Context

This part belongs to the Si5338 family of I2C-programmable clock generators. The 'C' indicates commercial temperature grade, while the 'B' prefix denotes a specific factory-preset configuration. The '-GM' suffix identifies the 24-lead QFN package type. This series is designed to reduce board space and power consumption compared to using multiple fixed-frequency crystals.

Replacement Considerations

Direct pin-to-pin replacements within the same family include other Si5338 variants with different factory presets (e.g., SI5338C-Bxxxxx-GM). Ensure the replacement part has the identical electrical characteristics and output configurations required by the design.
