SI5338C-B06074-GMR

Overview

The SI5338C-B06074-GMR is an I2C-programmable quad clock generator from Skyworks Solutions. It synthesizes any frequency on four output drivers using MultiSynth technology, achieving zero ppm precision. The device supports a core supply of 1.8 V, 2.5 V, or 3.3 V and operates within a temperature range of –40 to +85 °C. Key electrical parameters include a maximum input frequency of 710 MHz, typical phase jitter of 0.7 ps RMS, and a typical core supply current of 45 mA. It is housed in a compact 4 x 4 mm 24-lead QFN package.

Feature Summary

• MultiSynth technology enables independent, any-frequency synthesis with true zero ppm accuracy on four differential output drivers.
• Flexible input reference options including external crystals (8–30 MHz), CMOS (5–200 MHz), SSTL/HSTL (5–350 MHz), and differential inputs (5–710 MHz).
• Independently configurable outputs support various signal formats such as LVPECL, LVDS, HCSL, CMOS, and SSTL/HSTL with individual voltage levels.
• Features glitchless frequency adjustments in 1 ppm steps and independent phase adjustment with less than 20 ps resolution.

Applications

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

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm the pre-configured register settings. The 'GMR' suffix indicates tape and reel packaging. Confirm that the required output frequencies and formats match the factory-programmed configuration for this specific part number variant.

Selection Notes

Select this component when replacing multiple crystal oscillators with a single programmable source. Ensure the design accommodates the 4 x 4 mm QFN footprint and provides appropriate decoupling for the 1.8 V, 2.5 V, or 3.3 V core supply. Verify that the target application requires the specific frequency synthesis defined by the B06074 configuration code.

Part Context

This part belongs to the Si5338 family of low-jitter clock generators. The Si5338 series utilizes patented MultiSynth architecture to provide high-performance clock synthesis in a small form factor. It serves as a versatile solution for generating precise clock signals across various digital interfaces and communication protocols.

Replacement Considerations

Direct functional replacements within the same family include other Si5338 variants with different factory configurations. When substituting, ensure the new part supports the required output frequencies and formats, as the internal programming differs between specific model numbers.
