SI5338C-B05153-GM

Overview

The SI5338C-B05153-GM is a programmable quad clock generator utilizing MultiSynth technology. It synthesizes any frequency on four independent outputs with zero ppm precision. The device supports differential and single-ended formats including LVPECL, LVDS, HCSL, CMOS, SSTL, and HSTL. It operates from a 1.8 V, 2.5 V, or 3.3 V core supply with a typical current of 45 mA. Key electrical parameters include a maximum input frequency of 710 MHz, output frequencies up to 710 MHz for differential signals, and a typical RMS phase jitter of 0.7 ps. It is housed in a 24-lead QFN package.

Feature Summary

• MultiSynth technology enables independent, any-frequency synthesis on four output drivers with true zero ppm accuracy.
• Supports flexible input references: external crystals (8–30 MHz), CMOS (5–200 MHz), SSTL/HSTL (5–350 MHz), and differential inputs (5–710 MHz).
• Features low phase jitter of 0.7 ps RMS typical and independent output voltage configuration per driver (1.5, 1.8, 2.5, or 3.3 V).
• Includes independent frequency increment/decrement for glitchless adjustments and configurable spread spectrum on any output.

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

Procurement Notes

Verify the specific ordering suffix B05153 against the manufacturer's official documentation to confirm the exact pre-programmed frequency plan and output configuration. Confirm RoHS compliance status and moisture sensitivity level prior to procurement. Check for product change notifications that may affect pinout or electrical characteristics.

Selection Notes

Select this component when designing systems requiring multiple independent clock frequencies from a single IC. Ensure the required output signal format (LVPECL, LVDS, CMOS, etc.) matches the available driver options. Verify that the input reference source falls within the supported frequency ranges for the chosen input type.

Part Context

This part belongs to the Si5338 family of I2C-programmable clock generators. The 'C' designation typically indicates a specific performance grade or feature set within the series, while the alphanumeric suffix defines the factory-programmed register map. It replaces discrete crystal oscillators in complex digital designs.

Replacement Considerations

Direct replacements must be selected from the Si5338 family with compatible output configurations. Verify that alternative part numbers support the same output formats and frequency requirements. Consult the manufacturer's cross-reference guide for verified substitutes.
