SI5338C-B01917-GM

Overview

The SI5338C-B01917-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 flexible input references, including differential inputs up to 710 MHz and single-ended CMOS inputs up to 200 MHz. Outputs are configurable for LVPECL, LVDS, HCSL, CMOS, SSTL, or HSTL formats, supporting frequencies from 0.16 MHz to 710 MHz depending on the format. It operates on a single core supply of 1.8 V, 2.5 V, or 3.3 V, features low phase jitter of 0.7 ps RMS typical, and is housed in a 24-lead QFN package.

Feature Summary

• MultiSynth technology enables independent, any-frequency synthesis on four differential output drivers with true zero ppm accuracy.
• Flexible input reference options include external crystals (8–30 MHz), CMOS (5–200 MHz), SSTL/HSTL (5–350 MHz), and differential inputs (5–710 MHz).
• Highly-configurable output drivers support various signal formats: LVPECL/LVDS (up to 710 MHz), HCSL (up to 250 MHz), CMOS (up to 200 MHz), and SSTL/HSTL (up to 350 MHz).
• Features independent frequency increment/decrement for glitchless adjustments in 1 ppm steps and independent phase adjustment with <20 ps step accuracy.

Applications

• Ethernet switch/router clocking
• PCIe Gen1/2/3/4 common clock generation
• Processor and FPGA clocking
• Broadcast video/audio timing
• Telecom line cards

Procurement Notes

Verify the specific factory-programmed configuration associated with the B01917 suffix against the target design requirements. As this is a custom NVM part, ensure the programmed frequencies and output formats match the application specifications before integration.

Selection Notes

Select this component when multiple independent clock frequencies with precise synchronization are required. Ensure the desired output voltage levels (1.5, 1.8, 2.5, or 3.3 V) and signal formats (LVPECL, LVDS, etc.) align with the receiver's input specifications. Verify that the input reference source matches the supported frequency ranges for the chosen input pin type.

Part Context

This part belongs to the Si5338 family of I2C-programmable clock generators. The 'C' in the model number typically denotes a specific maximum input/output frequency limit (often 200 MHz for CMOS/SSTL variants, though the base device supports higher differential frequencies), while 'B01917' indicates a unique factory-programmed NVM configuration. The '-GM' suffix specifies the 24-lead QFN package.

Replacement Considerations

Direct replacements must be other Si5338 variants with compatible NVM configurations or reprogrammable equivalents like the SI5338A or SI5338J if the design allows for field programming via ClockBuilder Pro. Verify pinout compatibility and thermal characteristics.
